DESCRIPTION
Encode::Base2N supports Base64/32/16 encodings with or without url mode and padding. It's written in C++ and has also a C++ interface.
FUNCTIONS
Base64
Does Base64 encoding without padding
Does Base64 encoding without padding using so-called 'url' mode ('-' instead of '+' and '_' instead of '/')
Does Base64 encoding with padding
|
decode_base64($encoded)
Decodes Base64 (all possible variants)
|
Base32
Does Base32 encoding using lowercase alphabet
|
decode_base32($encoded)
Decodes Base32 (all possible variants)
|
Base16
Does Base16 encoding using lowercase alphabet
|
decode_base16($encoded)
Decodes Base16 (all possible variants)
|
Tests were performed on AMD Ryzen 9 3950X, Debian 10.
Benchmark code can be found in misc/mytest.plx
my $short = 'hello world hello world';
my $long = 'hello ' x 1000;

I found no module to compare with. Just testing this module's speed.
Benchmark: running decode_long, decode_short, encode_long, encode_short for at least 1 CPU seconds...
