NAME
|
||||
SHA1Init, SHA1Update, SHA1Final, SHA1Transform
|
||||
|
||||
SYNOPSIS
|
||||
#include <sys/types.h>
|
||||
|
||||
#include <sha1.h>
|
||||
|
||||
void SHA1Transform(
|
||||
uint32_t state[5],
|
||||
const unsigned char buffer[64]);
|
||||
|
||||
void SHA1Init(
|
||||
SHA1_CTX * context);
|
||||
|
||||
void SHA1Update(
|
||||
SHA1_CTX * context,
|
||||
const unsigned char *data,
|
||||
uint32_t len);
|
||||
|
||||
void SHA1Final(
|
||||
unsigned char digest[20],
|
||||
SHA1_CTX * context);
|
||||
|
||||
DESCRIPTION
|
||||
The SHA1 functions implement the NIST Secure Hash Algorithm (SHA-1), FIPS
|
||||
PUB 180-1. SHA-1 is used to generate a condensed representation of a
|
||||
message called a message digest. The algorithm takes a message less than
|
||||
2^64 bits as input and produces a 160-bit digest suitable for use as a
|
||||
digital signature.
|
||||
|
||||
The SHA1Init() function initializes a SHA1_CTX context for use with
|
||||
SHA1Update(), and SHA1Final(). The SHA1Update() function adds data of
|
||||
length len to the SHA1_CTX specified by context. SHA1Final() is called
|
||||
when all data has been added via SHA1Update() and stores a message digest
|
||||
in the digest parameter. When a null pointer is passed to SHA1Final() as
|
||||
first argument only the final padding will be applied and the current
|
||||
context can still be used with SHA1Update().
|
||||
|
||||
The SHA1Transform() function is used by SHA1Update() to hash 512-bit
|
||||
blocks and forms the core of the algorithm. Most programs should use the
|
||||
interface provided by SHA1Init(), SHA1Update() and SHA1Final() instead of
|
||||
calling SHA1Transform() directly.
|
||||
|
||||
EXAMPLES
|
||||
The follow code fragment will calculate the digest for the string "abc"
|
||||
which is ``0xa9993e36476816aba3e25717850c26c9cd0d89d''.
|
||||
|
||||
SHA1_CTX sha;
|
||||
uint8_t results[20];
|
||||
char *buf;
|
||||
int n;
|
||||
|
||||
buf = "abc";
|
||||
n = strlen(buf);
|
||||
SHA1Init(&sha);
|
||||
SHA1Update(&sha, (uint8_t *)buf, n);
|
||||
SHA1Final(results, &sha);
|
||||
|
||||
/* Print the digest as one long hex value */
|
||||
printf("0x");
|
||||
for (n = 0; n < 20; n++)
|
||||
printf("%02x", results[n]);
|
||||
putchar('\n');
|
||||
|
||||
Alternately, the helper functions could be used in the following way:
|
||||
|
||||
SHA1_CTX sha;
|
||||
uint8_t output[41];
|
||||
char *buf = "abc";
|
||||
|
||||
printf("0x%s", SHA1Data(buf, strlen(buf), output));
|
||||
|
||||
AUTHORS
|
||||
This implementation of SHA-1 was written by Steve Reid.
|
||||
|
||||
BUGS
|
||||
This implementation of SHA-1 has not been validated by NIST and as such
|
||||
is not in official compliance with the standard.
|
||||
|
||||
If a message digest is to be copied to a multi-byte type (ie: an array of
|
||||
five 32-bit integers) it will be necessary to perform byte swapping on
|
||||
little endian machines such as the i386, alpha, and VAX.
