Summary

Secure Hash Algorithm 1, abbreviated as SHA1 or SHA_1 or SHA-1 is a popular encryption scheme for a binary message. A binary message is a string consisting of 1’s and 0’s. This encryption is used in the authentication process to access the MySQL server databases. PurePerl stands for Pure Perl. It is Perl software without any C software underneath.

When a binary message of any length < 2^64 bits is input, the SHA-1 produces a 160-bit output called a Message Digest. The SHA-1 is called secure because it is computationally infeasible to find a message which corresponds to a given message digest, or to find two different messages which produce the same message digest. 160 bits is 20 bytes.

Downloading and Using
The SHA1 is in one file in PurePerl. It is in a Perl package called, Sha1 in a file called, Sha1.pm. The package (module) has one function, sha1() used in your script as follows:

use Mysql::Sha1;
my $message_digest = Sha1::sha1($binary_message);

Note: binary_message has to be text.

The file is in a zipped directory called, PurePerl-sha1.zip . To download it free, click the following link, after reading the agreement:
