MIME::Base64

Native implementation of MIME::Base64

Provides base64 encoding and decoding functions compatible with Perl’s MIME::Base64 module. Since PetaPerl does not support XS, this module is implemented directly in Rust.

Synopsis

use MIME::Base64;

my $encoded = encode_base64("Hello, World!");
my $decoded = decode_base64($encoded);

# Suppress line breaks
my $oneline = encode_base64($data, "");

# URL-safe variant
use MIME::Base64 'encode_base64url';
my $token = encode_base64url($data);

Functions

encode_base64

Encode binary data to base64. An optional second argument specifies the end-of-line sequence inserted every 76 characters (default: “\n”). Pass “” to suppress line breaks.

use MIME::Base64;
my $encoded = encode_base64("Hello, World!");
my $oneline = encode_base64($data, "");

decode_base64

Decode a base64-encoded string back to the original binary data. Whitespace in the input is silently ignored.

use MIME::Base64;
my $decoded = decode_base64("SGVsbG8sIFdvcmxkIQ==");

encode_base64url

Encode binary data using the URL-safe base64 alphabet (- and _ instead of + and /), without padding or line breaks.

use MIME::Base64 'encode_base64url';
my $token = encode_base64url($data);

decode_base64url

Decode a URL-safe base64-encoded string back to binary data.

use MIME::Base64 'decode_base64url';
my $data = decode_base64url($token);

encoded_base64_length

Return the length of the string that encode_base64 would produce for the given data, without actually encoding it.

decoded_base64_length

Return the length of the data that decode_base64 would produce for the given encoded string, without actually decoding it.

Standard Base64 Alphabet

Standard: A-Z, a-z, 0-9, +, / with = padding URL-safe: A-Z, a-z, 0-9, -, _ without padding
