Hi,
I'm trying to use the EVP AES wrap implementations from openssl (e.g. EVP_aes_128/192/256_wrap()) but I'm getting the following error in EVP_EncryptInit_ex() f:
error:0607B0AA:digital envelope routines:EVP_CipherInit_ex:wrap mode not allowed
I've search the documentation for examples or guidance but I couldn't find anything related to this.
Any experienced the same issue ?
My pseudo code is:
EVP_CIPHER_CTX ctx;
EVP_CIPHER_CTX_init(&ctx);
if (EVP_EncryptInit_ex(&ctx, EVP_aes_128_wrap(), 0, keyEncriptionKey, iv) != 1)
if (EVP_EncryptInit_ex(&ctx, EVP_aes_128_wrap(), 0, keyEncriptionKey, iv) != 1)
// process error
if ( EVP_EncryptUpdate(&ctx, bufferOut, &processedSize, plaintext, plaintextSize) != 1)
// process error
if (EVP_EncryptFinal_ex(&ctx, bufferOut + processedSize, &tmpSize) != 1)
// process error
EVP_CIPHER_CTX_cleanup(&ctx);
if (EVP_EncryptFinal_ex(&ctx, bufferOut + processedSize, &tmpSize) != 1)
// process error
EVP_CIPHER_CTX_cleanup(&ctx);
Regards,
Luís
