C++ (Cpp) cipher_set_key Examples

Example #1

File: cipher.c Project: long5313828/ythtbbs

void cipher_set_key_string(CipherContext * context, int cipher, const char *passphrase, int for_encryption)
{
    struct MD5Context md;
    unsigned char digest[16];

    MD5Init(&md);
    MD5Update(&md, (const unsigned char *) passphrase, strlen(passphrase));
    MD5Final(digest, &md);

    cipher_set_key(context, cipher, digest, 16, for_encryption);

    memset(digest, 0, sizeof(digest));
    memset(&md, 0, sizeof(md));
}

Example #2

{
	MD5_CTX md;
	unsigned char digest[16];

	MD5_Init(&md);
	MD5_Update(&md, (const unsigned char *) passphrase, strlen(passphrase));
