Incorrect decrypted content
Posted: Thu Jan 28, 2021 1:25 pm
Hi,
I have a file encrypted with AES Crypt. I enter a password to decrypt the file with AES Crypt and I get no error (code 0).
But the content of the result file is incorrect, seems random data.The entropy of the result file is 7.9 with Sysinternals sigcheck.
I think the version of AES Crypt is 3.0.9 because of encrypted file header.
I use the Windows console version 3.0.9 to decrypt the file: aescrypt.exe -d -o decrypted.bin encrypted.aes
The file to recover is an ExDupe archive: http://www.quicklz.com/exdupe/
I tried with 2 files from 2 HDD, same behavior. I don't understand why the decrypted content is incorrect.
I'm not 100% sure of the password. Is password checking reliable in AES Crypt?
Maybe the encrypted file is corrupted. Is there any CRC check implemented in AES Crypt?
Thank you.
