BinaryDecodeUU(<encoded>)

Description

Decodes a UUEncode string back to its original binary representation.

Parameters

<encoded> The UUEncode string to decode.

Return Value

Success: Returns decoded binary string.
Failure: Returns empty binary string.

Remarks

UUEncoding, also known as Unix-to-Unix encoding, is a binary-to-text encoding scheme used in early Unix systems for converting binary files into a printable ASCII format. It involves converting 6 bits of binary data into an ASCII character representation using a fixed set of 64 characters. The encoded data is larger than the original binary data, and the decoding process reverses the encoding steps. While UUEncoding is a widely supported method, it is not efficient in terms of data size and does not provide data protection or security. Its usage has diminished with the advancements in file transfer mechanisms and binary-safe protocols.

my $str = Bin('a' rr 'f', 'A' rr 'F', '0' rr '9');
my $encoded = BinaryEncodeUu($str);
say $encoded;
my $decoded = BinaryDecodeUu($encoded);
say $decoded;
