md5

The md5() function calculates the md5 hash of a string.

PHP

echo md5('apple');
// => 1f3870be274f6c49b3e31a0c6728957f

MD5 encryption can be done using the Digest library in Ruby. To use the Digest library, just require it…

Ruby

require 'digest/md5';
 
print Digest::MD5.hexdigest('apple');
 
# => 1f3870be274f6c49b3e31a0c6728957f
