Function Documentation

void sha1_buffer	(	const char *	buffer,
		int	length,
		unsigned char	digest[SHA1_DIGEST_LENGTH]
	)

Checksum a memory buffer.

Note that this function produces a digest in binary form which must be converted to a human readable form with sha1_string.

Parameters:

buffer	Pointer to a memory buffer.
length	Length of the buffer in bytes.
digest	Pointer to a buffer to store the digest.

int sha1_file	(	const char *	filename,
		unsigned char	digest[SHA1_DIGEST_LENGTH]
	)

Checksum a local file.

Note that this function produces a digest in binary form which must be converted to a human readable form with sha1_string.

Parameters:

filename	Path to the file to checksum.
digest	Pointer to a buffer to store the digest.

Returns:

One on success, zero on failure.

const char* sha1_string

(

unsigned char

digest[SHA1_DIGEST_LENGTH]

)

Convert an SHA1 digest into a printable string.

Parameters:

digest

A binary digest returned from sha1_file.

Returns:

A static pointer to a human readable form of the digest.
