NAME

6       EVP_MD-common - The OpenSSL EVP_MD implementations, common things
7

DESCRIPTION

9       All the OpenSSL EVP_MD implementations understand the following
10       OSSL_PARAM(3) entries that are gettable with EVP_MD_get_params(3), as
11       well as these:
12
13       "blocksize" (OSSL_DIGEST_PARAM_BLOCK_SIZE) <unsigned integer>
14           The digest block size.  The length of the "blocksize" parameter
15           should not exceed that of a size_t.
16
17           This value can also be retrieved with EVP_MD_get_block_size(3).
18
19       "size" (OSSL_DIGEST_PARAM_SIZE) <unsigned integer>
20           The digest output size.  The length of the "size" parameter should
21           not exceed that of a size_t.
22
23           This value can also be retrieved with EVP_MD_get_size(3).
24
25       "flags" (OSSL_DIGEST_PARAM_FLAGS) <unsigned integer>
26           Diverse flags that describe exceptional behaviour for the digest.
27           These flags are described in "DESCRIPTION" in
28           EVP_MD_meth_set_flags(3).
29
30           The length of the "flags" parameter should equal that of an
31           unsigned long int.
32
33           This value can also be retrieved with EVP_MD_get_flags(3).
