-=head1 NAME
-
-SHA1, SHA1_Init, SHA1_Update, SHA1_Final - Secure Hash Algorithm
-
-=head1 SYNOPSIS
-
- #include <openssl/sha.h>
-
- unsigned char *SHA1(const unsigned char *d, unsigned long n,
-                  unsigned char *md);
-
- int SHA1_Init(SHA_CTX *c);
- int SHA1_Update(SHA_CTX *c, const void *data,
-                  unsigned long len);
- int SHA1_Final(unsigned char *md, SHA_CTX *c);
-
-=head1 DESCRIPTION
-
-SHA-1 (Secure Hash Algorithm) is a cryptographic hash function with a
-160 bit output.
-
-SHA1() computes the SHA-1 message digest of the B<n>
-bytes at B<d> and places it in B<md> (which must have space for
-SHA_DIGEST_LENGTH == 20 bytes of output). If B<md> is NULL, the digest
-is placed in a static array.
-
-The following functions may be used if the message is not completely
-stored in memory:
-
-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>.
-
-Applications should use the higher level functions
-L<EVP_DigestInit(3)|EVP_DigestInit(3)>
-etc. instead of calling the hash functions directly.
-
-The predecessor of SHA-1, SHA, is also implemented, but it should be
-used only when backward compatibility is required.
-
-=head1 RETURN VALUES
-
-SHA1() returns a pointer to the hash value. 
-
-SHA1_Init(), SHA1_Update() and SHA1_Final() return 1 for success, 0 otherwise.
