Routines for computing MD5 checksums.


Function Documentation

void md5_buffer ( const void *  buffer,
size_t  length,
unsigned char  digest[MD5_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 md5_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 md5_file ( const char *  filename,
unsigned char  digest[MD5_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 md5_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* md5_string ( unsigned char  digest[MD5_DIGEST_LENGTH]  ) 

Convert an MD5 digest into a printable string.

Parameters:
digest A binary digest returned from md5_file, md5_buffer, or chirp_reli_md5.
Returns:
A static pointer to a human readable form of the digest.
