Hallo,
I am using the symmetric cypher functions to encrypt and then
decrypt a string. The cipher is "aes-256-cbc". When I try to decrypt
the string, I get this error:
error 06065064: digital envelope routines: EVP_DecryptFinal_ex: bad decrypt
I am using the same key and same iv. The string is the same
because it has a hmac field, which is checked. The string to be
decrypted is padded to 48 bytes by the encryption routine, so I guess
it's not a padding error. The call to EVP_CipherUpdate runs fine, but
the error occurs in the EVP_CipherFinal_ex function. I don't know what
else may be going wrong. Any help is appreciated.
Thanks,
