Hashids - generate short hashes from numbers
use Hashids; my $hashids = Hashids->new(salt => "this is my salt"); # encrypt a single number my $hash = $hashids->encrypt(123); # 'a79' my $number = $hashids->decrypt('a79'); # 123 # or a list $hash = $hashids->encrypt(1, 2, 3); # 'eGtrS8' my $numbers = $hashids->decrypt('eGtrS8'); # [1, 2, 3]
Hashids was designed for use in URL shortening, tracking stuff, validating accounts or making pages private (through abstraction.) Instead of showing items as
3, you could show them as
Aaco9cy5. Hashes depend on your salt value.
Make a new Hashids object. This constructor accepts a few options:
Salt string, this should be unique per Hashid object.
Alphabet set to use. This is optional as Hashids comes with a default set suitable for URL shortening.
Minimum hash length. Use this to control how long the generated hash string should be.
Encrypt a single number (or a list of numbers) into a hash string.
Decrypt a hash string into its number (or numbers.) Returns either a simple scalar if it is a single number, or an arrayref of numbers if it decrypted a set. Use ref on the result to ensure proper usage.
