4.2 Hash Algorithms

Hash (message digest) algorithms are used to compress a long message to make it suitable for public key cryptography.

Data type: enum gpgme_hash_algo_t ¶

The gpgme_hash_algo_t type specifies the set of all hash algorithms that are supported by GPGME. Possible values are:

GPGME_MD_MD5

GPGME_MD_SHA1

GPGME_MD_RMD160

GPGME_MD_MD2

GPGME_MD_TIGER

GPGME_MD_HAVAL

GPGME_MD_SHA256

GPGME_MD_SHA384

GPGME_MD_SHA512

GPGME_MD_SHA224

SINCE: 1.5.0

GPGME_MD_MD4

GPGME_MD_CRC32

GPGME_MD_CRC32_RFC1510

GPGME_MD_CRC24_RFC2440

Function: const char * gpgme_hash_algo_name (gpgme_hash_algo_t algo) ¶

The function gpgme_hash_algo_name returns a pointer to a statically allocated string containing a description of the hash algorithm algo. This string can be used to output the name of the hash algorithm to the user.

If algo is not a valid hash algorithm, NULL is returned.
