.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "EVP_BLAKE2B512 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
EVP_blake2b512, EVP_blake2s256 \- BLAKE2 For EVP Header "SYNOPSIS" .Vb 1 #include <openssl/evp.h> \& const EVP_MD *EVP_blake2b512(void); const EVP_MD *EVP_blake2s256(void); .Ve Header "DESCRIPTION" \s-1BLAKE2\s0 is an improved version of \s-1BLAKE,\s0 which was submitted to the \s-1NIST SHA-3\s0 algorithm competition. The BLAKE2s and BLAKE2b algorithms are described in \s-1RFC 7693.\s0 Item "EVP_blake2s256()" The BLAKE2s algorithm that produces a 256-bit output from a given input. Item "EVP_blake2b512()" The BLAKE2b algorithm that produces a 512-bit output from a given input. Header "RETURN VALUES" These functions return a \s-1EVP_MD\s0 structure that contains the implementation of the symmetric cipher. See EVP_MD_meth_new\|(3) for details of the \s-1EVP_MD\s0 structure. Header "CONFORMING TO" \s-1RFC 7693.\s0 Header "NOTES" While the BLAKE2b and BLAKE2s algorithms supports a variable length digest, this implementation outputs a digest of a fixed length (the maximum length supported), which is 512-bits for BLAKE2b and 256-bits for BLAKE2s.
