Re^2: Would Like Recommendation for an SHA256 module

Digest::SHA's functional interface provides simple and easy access to common tasks.

Don't do it that way. Instead, use Digest as a base module, and you can use any compatible Digest::* module as a plug-in. That way, your code doesn't have to change when switching between hash implementations — only the specification of what hash to use (a string), in the call to new.

See also the speed comparison table in that same module.

use Digest as a base module I'm a novice when it comes to modules, so I'm not sure what you mean. Are you suggesting something different than just putting `use Digest::SHA` or `use Digest::SHA::PurePerl` at the top of my script? They both say they use the same interface as `Digest::` TheEnigma	[reply] [d/l] [select]

Install Digest and Digest::SHA. Don't use Digest::SHA directly. Use the following code instead: `use Digest (); my $data = ...; my $hasher = Digest->new('SHA-256'); $hasher->add($data); $hasher->b64digest(); # or ->digest or ->hexdigest` [download]	[reply] [d/l]
