7
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).
