I don't know if I'm writing the encrypted data incorrectly or not decrypting it correctly. Target Audience. Hello, any updates? via command-line on Mac, you can run this in the terminal: openssl enc -d -aes-128-cbc -in encrypted.file -out decrypted.file, You can also download AESCrypt: https://www.aescrypt.com/download/. If I'm not initialising the vi correctly from my code, could you please guide me? and to understand where our visitors are coming from. Can anyone suggest where I'm going wrong? Here is a simple test project. No, it's not the case. affirm you're at least 16 years old or have consent from a parent or guardian. I have only the key used to crypt the image. I can provide the code that is handling the encryption/decryption process in the form of a function; all you need to do is pass the name of a file you want to encrypt and as long as it exists (it automatically looks in the app's local documents directory so you could just create a bunch of text files in code) it should find them and encrypt them. In turn, when a passphrase is used by the openssl encryption routine, a magic and salt is put in front of the encrypted result. Solo un file danneggiato, o uno crittografato con, Nel secondo comando, non stai decodificando (, /programming/22610761/aes-simple-encrypt-in-java-decrypt-with-openssl/55884564#55884564. As standard openssl is used for encrypting the files, you can use it to decrypt your files after you download the files using other utilities without using a NAS. We’ll occasionally send you account related emails. Successfully merging a pull request may close this issue. As far as I'm aware, the vi in my code above matches what AES.blocksize() returns anyway. $ echo -n 'redacted-cipher-data' | base64 -d > cipherdata $ echo 'redacted-cipher-data' > cipherdata.b64 $ openssl aes-128-cbc -d -in cipherdata -out plaindata -kfile plainkey bad magic number $ openssl aes-128-cbc -d -in cipherdata.b64 -out plaindata -kfile plainkey bad magic number Se hai crittografato con OpenSSL <= 1.0.2 e stai decrittografando con OpenSSL 1.1.0, probabilmente è questo: https://www.openssl.org/docs/faq.html#USER3. Thanks. pem file using openssl:. To compare output with the OpenSSL first you should know how OpenSSL works. because it's not encrypted data here. I then pass this into the AES.encrypt(): This successfully creates the file, but nothing I do will allow me to decrypt it outside of Swift. Once decrypted, I then save the data back to disk as a new file, exactly the same way that I save the encrypted data. > openssl enc -d -pass pass:your_passphrase -aes-256-cbc -in private.img.000 -out private.img.dec.000 > shown on the wiki, but even with what was definitely my encryption password, I'm getting bad magic number errors from openssl. E il comando seguente lo ha risolto e mi ha dato piacere: La causa generale di questo errore è che la chiave calcolata da OpenSSL dalla password è errata, il che significa che non corrisponde alla chiave che ha crittografato i dati. I don't have any business in this project so I just can do as much as I can in my spare time and nothing more. The text was updated successfully, but these errors were encountered: I'm not sure I understand? Is this intentional or am I misunderstanding? Then I unbind the sham driver and still got the bad decrypt message. The problem is with the key. I'm generating the AES file via this library, not openssl (although I am attempting to decrypt it via openssl). But a problem is still making me mad. Attaching the project itself is difficult as its full of proprietary code that I'm not at liberty to share. Have a question about this project? Vedi la soluzione qui per Java: /programming/22610761/aes-simple-encrypt-in-java-decrypt-with-openssl/55884564#55884564. I have a database that I am loading in as a Data object. Is the 5 MB static resource size limit 5,242,880 bytes or 5,000,000 bytes? I don’t know what block cipher mode DCI uses, and if I need the IV. Post by barchia Hi to * I try to decode a file that is encripted with des3 cipher, the file is encoded with .NET framework, the key is 128 bit The same issue occurs. Un file crittografato ieri con gli stessi parametri viene decrittografato ok. Cosa sarebbe potuto succedere? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. - I try to decrypt it with OpenSSL: > openssl enc -d -aes-256-cbc -in test.txt -out test-decrypted.txt -k test This gives the error: "bad magic number" I tried various options to OpenSSL, like "-md sha" (to make sure the key/iv pair is generated with SHA), -nosalt, and … openssl aes-256-cbc -d -in hotmama.tar.bz2.enc -out hotmama.tar.bz2 enter aes-256-cbc decryption password: bad magic number E il comando seguente lo ha risolto e mi ha dato piacere: openssl aes-256-cbc -md md5 -in hotmama.tar.bz2.enc -out hotmama.tar.bz2 enter aes-256-cbc encryption password: Verifying - enter aes-256-cbc encryption password: to your account. Can you attach a project with the code with CryptoSwift and OpenSSL? I tried the command openssl enc -d -pass pass:your_passphrase -aes-256-cbc -in private.img.000 -out private.img.dec.000 shown on the wiki, but even with what was definitely my encryption password, I'm getting bad magic number errors from openssl.

I hope that help you in your adventure. Privacy policy. Error in decryption OpenSSL encrypted file, CryptoSwift produces different output to OpenSSL, IV is derived from the password if not given, MD5 digest is used for key derivation by default. I'm having issues decrypting a database file encrypted via AES. Ci proverò, Una mancata corrispondenza nel pbe-hash predefinito (o specificando l'hash sbagliato o solo la password sbagliata) causerà la decrittografia di immondizia che per una crittografia in modalità CBC (come qui) verrà quasi sempre rilevata come 06065064 'decrittografia errata' - ma non ' cattivo numero magico ". The -k argument expects a passphrase, not a file. privacy statement. Prova ad aggiungere il -md md5tuo comando di decrittazione. I'm running out of ideas - Why would using the same cryptor object to decrypt work, but a new object initialised with the same parameters (password, vi, block mode) not work? I have also tried copying verbatim the example given in this project's playground: let aes = try AES(key: "passwordpassword", iv: "drowssapdrowssap") // aes128 let ciphertext = try aes.encrypt(Array("Nullam quis risus eget urna mollis ornare vel eu leo. ".utf8)) let encryptedData = Data(ciphertext) i trying decrypt aes-256-cbc , keeps giving me errors "error reading input file" and, "bad magic number". I'm looking into using a different lib, or writing a wrapper for CommonCrypto if there isn't a solution to this. Openssl web assembly Openssl web assembly. Any news on this? Already on GitHub? I've commented out the stuff that isn't being used so it's as simple as possible: @jimidobson you can create empty project with the issue, though. OpenSSL 1.1.1b warning: Using -iter or -pbkdf2 would be better while decrypting a file encrypted using OpenSSL 1.1.0g Hot Network Questions Can a process run regardless of any shell? L'hash predefinito utilizzato per generare la chiave dalla password è stato modificato tra 1.0.2 e 1.1.0. Let's build CryptoSwift code and corresponding OpenSSL command: now you can compare the output with OpenSSL command: echo -n "Nullam quis risus eget urna mollis ornare vel eu leo." You can read details in our @krzyzanowskim I've performed another test, this time creating an identical copy of the aes object but using it to decrypt the data: The resulting data written to the decrypted file is garbled - So for some reason, using the exact same encryptor to encrypt, read back in and decrypt the data works, but creating a new instance of the AES cryptor and using that to decrypt results in nonsense. ... but all 51 return "bad magic number", so as I mentioned before this seems not to be a standard openssl encryption. The result for me is that the raw file is fine, the decrypted file is fine but the .aes cannot be decrypted via AESCrypt or openssl. How do u decrypt with OpenSSL? Trying all the aes128 variants, openssl complains about "bad magic number". grazie temevo che potesse essere qualcosa del genere Siamo in una situazione insolita che vuole ripristinare qualcosa di così vecchio. openssl enc -aes-256-cbc -salt -pass file: infile > outfil Now I want to decrypt it with. I’m trying to decrypt an image crypted with aes128 following the DCI (digital cinema) rules. @jimidobson really, feel free to use whatever you want. Also, I've tried encryption using the aes.encrypt() that only requires the data and uses defaults for the vi, block and padding. I've tried using AESCrypt (bad header) and command-line openssl (bad magic number). Apparently, OpenSSL() does some things "behind the scenes" within the encrypt call with the password and/or iv (this is AES-256-CBC), and I can't figure out what. is let encryptedData = Data(data) a typo? This and OpenSSL part. This suggests that the library encryption/decryption process seems to work as long as only the library touches it, but the output is not being recognised by any other exterior AES decryption software or utility. Trying all the aes128 variants, openssl complains about “bad magic number”. This is sort of a pain to do with openssl, because openssl's encryption makes assumptions about padding and deriving a salted key from the entered password that you have to deliberately turn off. pem -check -noout Enter pass phrase for testkey. That runs with a GUI or command-line if you prefer. | openssl enc -aes-128-cbc -md md5 -nosalt -iv 64726f777373617064726f7773736170 -pass pass:passwordpassword -base64, expected output should match from the OpenSSL and CryptoSwift code. AES - simple encrypt in Java, decrypt with openssl. Maybe I'm missing a step? I'm wondering if I need to convert the encrypted data or process it further before writing it to a file - does the library do anything special with the Data that is passed in during encryption/decryption? By continuing, you consent to our use of cookies and other tracking technologies and By clicking “Sign up for GitHub”, you agree to our terms of service and It's much easier to do in python with say PyCrypto, where these assumptions aren't made. I have also tried copying verbatim the example given in this project's playground: I'm at a loss as to what I'm doing wrong; I'm not sure if I'm writing the data incorrectly or decrypting it incorrectly. org> Date: 2006-09-11 23:44:41 Message-ID: 20060911234440.GA6764 openssl ! @krzyzanowskim That was the missing step I needed - I was lacking the MD5 digest, and I wasn't passing the correct parameters to openssl, specifically, the -nosalt and I wasn't providing the IV. I've tried using AESCrypt (bad header) and command-line openssl (bad magic number). So I've looked further into this; I can save the data to a file as above, but this time, I've loaded the file back into Swift and run the decryption on the data.
