A fast Base64 encoder and decoder as a Ruby gem.
How fast? Try it yourself, execute:
$ rake benchmark
When compared to Ruby's own Base64 module, expect a 4x speedup in encoding, and a 2x speedup in decoding. YMMV.
Ob64 uses libbase64 under the hood. Originally developed by aklomp, here we started from BurningEnlightenment's fork. libbase64 takes advantage of SIMD (AVX2, NEON, AArch64/NEON, SSSE3, SSE4.1, SSE4.2, AVX) acceleration available on x86, x86-64, and ARM systems.
Add this line to your application's Gemfile:
gem 'ob64'And then execute:
$ bundle install
Or install it yourself as:
$ gem install ob64
Requires CMake and a C99 compiler.
WARNING: Only tested on Linux and x86-64.
require "ob64"
bin1 = "This is data!"
string = Ob64.encode(bin1)
# string = "VGhpcyBpcyBkYXRhIQ=="
bin2 = Ob64.decode(string)
puts "Same? #{bin1 == bin2}"
# "Same? true"If you want to replace Ruby's own Base64 module with Ob64 (NOT RECOMMENDED!):
require "ob64/core_ext"
# It does NOT replace:
# - Base64.encode64
# - Base64.decode64See YARD documentation.
See {file:CHANGELOG.md}.
After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
