NAME

EVP_MD-common - The OpenSSL EVP_MD implementations, common things

DESCRIPTION

All the OpenSSL EVP_MD implementations understand the following EVP_MD_get_params(3):

"blocksize" (OSSL_DIGEST_PARAM_BLOCK_SIZE) <unsigned integer>

The digest block size. The length of the "blocksize" parameter should not exceed that of a size_t.

This value can also be retrieved with "size" (OSSL_DIGEST_PARAM_SIZE) <unsigned integer>

The digest output size. The length of the "size" parameter should not exceed that of a size_t.

This value can also be retrieved with "flags" (OSSL_DIGEST_PARAM_FLAGS) <unsigned integer>

Diverse flags that describe exceptional behaviour for the digest. These flags are described in EVP_MD_flags(3).
