Template::Plugin::Digest::MD5 0.03

Template::Plugin::Digest::MD5 is a TT2 interface to the MD5 Algorithm.

SYNOPSIS

[% USE Digest.MD5 -%]
[% checksum = content FILTER md5 -%]
[% checksum = content FILTER md5_hex -%]
[% checksum = content FILTER md5_base64 -%]
[% checksum = content.md5 -%]
[% checksum = content.md5_hex -%]
[% checksum = content.md5_base64 -%]

The Digest.MD5 Template Toolkit plugin provides access to the MD5 algorithm via the Digest::MD5 module. It is used like a plugin but installs filters and vmethods into the current context.

When you invoke

[% USE Digest.MD5 %]

the following filters (and vmethods of the same name) are installed into the current context:

md5

Calculate the MD5 digest of the input, and return it in binary form. The returned string will be 16 bytes long.

md5_hex

Same as md5, but will return the digest in hexadecimal form. The length of the returned string will be 32 and it will only contain characters from this set: '0'..'9' and 'a'..'f'.

md5_base64

Same as md5, but will return the digest as a base64 encoded string. The length of the returned string will be 22 and it will only contain characters from this set: 'A'..'Z', 'a'..'z', '0'..'9', '+' and '/'.

Note that the base64 encoded string returned is not padded to be a multiple of 4 bytes long. If you want interoperability with other base64 encoded md5 digests you might want to append the redundant string "==" to the result.
As the filters are also available as vmethods the following are all equivalent:

FILTER md5_hex; content; END;
content FILTER md5_hex;
content.md5_base64;
