hash

get checksum of file or string using various digest algorithms

Syntax

res = hash(fd, algorithm)
res = hash(string, algorithm)

Arguments

res: hash result (a string)
fd: a matrix of file descriptors returned by the function mopen.
string: a string or a matrix of strings
algorithm: a string (the hashing algorithm)

Description

hash get the checksum of a file or a string using the hashing function algorithm. The available functions are:

'crc32'	crc32 chechsum
'md5'	Message-Digest Algorithm 5
'sha1'	Secure Hash Algorithm 1 (160 bits)
'sha2', 'sha256'	Secure Hash Algorithm 2 (256 bits)
'sha3-224'	Secure Hash Algorithm 3 (224 bits)
'sha3-256'	Secure Hash Algorithm 3 (256 bits)
'sha3-384'	Secure Hash Algorithm 3 (384 bits)
'sha3-512'	Secure Hash Algorithm 3 (512 bits)

Examples

hash('hello world', 'md5')
hash('hello world', 'sha256')
hash(['hello';'world'], 'sha3-256')

fp = mopen(SCI+'/modules/core/etc/core.start')
hash(fp ,'sha256')
mclose(fp)
