(E.g. when using ERR_print_errors() - see the documentation for how to use) Ger Hi Ger, I tried your suggestion: ... ... int r2 = EVP_CipherInit_ex(&ctx, cipher, NULL, key, iv, DECRYPT); ERR_print_errors_fp(stderr); ... ... The output was: 933945:error:0607C084:lib(6):func(124):reason(132):evp_enc.c:523: 933945:error:0607B086:lib(6):func(123):reason(134):evp_enc.c:170: [EMAIL PROTECTED] openssl errstr 0607C084 error:0607C084:digital envelope routines:EVP_CIPHER_CTX_ctrl:ctrl not implemented [EMAIL PROTECTED] openssl errstr 0607B086 error:0607B086:digital envelope routines:EVP_CipherInit:initialization error It says "ctrl not implemented". This looks very strange to me because the same function (EVP_CipherInit_ex) works okay in the encryption stage, this fails only in the decryption stage. What is the meaning of "ctrl not implemented"? And why would this be not implemented in decryption stage, but be implemented in encryption stage? Any pointers on how to resolve or fix this problem? Thanks.
