It's much easier to do in python with say PyCrypto, where these assumptions aren't made. But a problem is still making me mad. affirm you're at least 16 years old or have consent from a parent or guardian. 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. 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. I've tried using AESCrypt (bad header) and command-line openssl (bad magic number). This and OpenSSL part. > 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 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. @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. I can take a look at this. pem -check -noout Enter pass phrase for testkey. I hope that help you in your adventure. 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 ". Privacy policy. Here is a simple test project. Already on GitHub? As far as I'm aware, the vi in my code above matches what AES.blocksize() returns anyway. 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. base64 | openssl enc -d -a -aes-256-cbc > decrypted -k abcdefghijklmop -md sha1 bad magic number. … Then I unbind the sham driver and still got the bad decrypt message. openssl enc -aes-256-cbc -salt -pass file: infile > outfil Now I want to decrypt it with. | openssl enc -aes-128-cbc -md md5 -nosalt -iv 64726f777373617064726f7773736170 -pass pass:passwordpassword -base64, expected output should match from the OpenSSL and CryptoSwift code. 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. to your account. 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. I have a database that I am loading in as a Data object. Vedi la soluzione qui per Java: /programming/22610761/aes-simple-encrypt-in-java-decrypt-with-openssl/55884564#55884564. Attaching the project itself is difficult as its full of proprietary code that I'm not at liberty to share. Target Audience. Ad aprile ho crittografato un file usando il comando. Openssl web assembly Openssl web assembly. to show you personalized content and targeted ads, to analyze our website traffic, 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. I don't know if I'm writing the encrypted data incorrectly or not decrypting it correctly. 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? $ 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 Thanks.
