New function BN_pseudo_rand(). Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when generating DSA primes (why not use BN_is_prime()?)

=head1 NAME
|
|
|
|
SHA1_Init, SHA1_Update_SHA1_Final - Compute SHA1 hash
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/sha.h>
|
|
|
|
void SHA1_Init(SHA_CTX *c);
|
|
void SHA1_Update(SHA_CTX *c, const unsigned char *data,
|
|
unsigned long len);
|
|
void SHA1_Final(unsigned char *md, SHA_CTX *c);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SHA1_Init() initializes a B<SHA_CTX> structure.
|
|
|
|
SHA1_Update() can be called repeatedly with chunks of the message to
|
|
be hashed (B<len> bytes at B<data>).
|
|
|
|
SHA1_Final() places the message digest in B<md>, which must have space
|
|
for SHA_DIGEST_LENGTH == 20 bytes of output, and erases the B<SHA_CTX>.
|
|
|
|
When the entire message is available at one time, L<SHA1(3)|SHA(1)>
|
|
can be used.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SHA1_Init(), SHA1_Update() and SHA1_Final() do not return values.
|
|
|
|
=head1 HISTORY
|
|
|
|
SHA1_Init(), SHA1_Update() and SHA1_Final()are available in all
|
|
versions of SSLeay and OpenSSL.
