Name
SPVM::MIME::Base64 - Base64 Encoding/Decoding
Description
The MIME::Base64 class of SPVM has methods for Base64 encoding/decoding.
Usage
use MIME::Base64;
my $encoded = MIME::Base64->encode_base64('Aladdin:open sesame');
my $decoded = MIME::Base64->decode_base64($encoded);Class Methods
encode_base64
static method encode_base64 : string ($string : string, $eol : string = undef);
Encodes the string $string to a Base64 string, and returns it.
The argument $eol is the line-ending sequence to use. It is optional and defaults to \n.
The returned encoded string is broken into lines of no more than 76 characters each and it will end with $eol unless it is empty.
Pass an empty string as the $eol if you do not want the encoded string to be broken into lines.
Exceptions:
$string must be defined. Otherwise an exception is thrown.
decode_base64
static method decode_base64 : string ($string : string);
Decodes a Base64 string $string to a string, and returns it.
Any character not part of the 65-character base64 subset is silently ignored. Characters occurring after a = padding character are never decoded.
Exceptions:
$string must be defined. Otherwise an exception is thrown.
encoded_base64_length
static method encoded_base64_length : int ($string : string, $eol : string = undef);
Returns the length that the encoded string would have without actually encoding it.
This will return the same value as the length of the returned value of the "encode_base64" method, but should be more efficient.
Exceptions:
$string must be defined. Otherwise an exception is thrown.
decoded_base64_length
static method decoded_base64_length : int ($string : string);
Returns the length that the decoded string would have without actually decoding it.
This will return the same value as the length of the returned value of the "decode_base64" method, but should be more efficient.
Exceptions:
$string must be defined. Otherwise an exception is thrown.
