If the F register is >0, we'll generate index entries on stderr for

For nroff, turn off justification. Always turn off hyphenation; it makesway too many mistakes in technical documents.
NAME
EVP_MD-common - The OpenSSL EVP_MD implementations, common things
DESCRIPTION
Header "DESCRIPTION" All the OpenSSL EVP_MD implementations understand the following
\fBOSSL_PARAM\|(3) entries that are
gettable with EVP_MD_get_params\|(3), as well as these:
"""blocksize"" (OSSL_DIGEST_PARAM_BLOCK_SIZE) <unsigned integer>" 4
Item """blocksize"" (OSSL_DIGEST_PARAM_BLOCK_SIZE) <unsigned integer>" The digest block size.
The length of the "blocksize" parameter should not exceed that of a
\fBsize_t.
.Sp
This value can also be retrieved with EVP_MD_get_block_size\|(3).
"""size"" (OSSL_DIGEST_PARAM_SIZE) <unsigned integer>" 4
Item """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.
.Sp
This value can also be retrieved with EVP_MD_get_size\|(3).
"""flags"" (OSSL_DIGEST_PARAM_FLAGS) <unsigned integer>" 4
Item """flags"" (OSSL_DIGEST_PARAM_FLAGS) <unsigned integer>" Diverse flags that describe exceptional behaviour for the digest.
These flags are described in "DESCRIPTION" in EVP_MD_meth_set_flags\|(3).
.Sp
The length of the "flags" parameter should equal that of an
\fBunsigned long int.
.Sp
This value can also be retrieved with EVP_MD_get_flags\|(3).
