== Riff Riff is a wrapper around diff that highlights not only which lines have changed, but also which parts of the lines that have changed. = Usage $ git diff | riff Or if you do... $ git config --global pager.diff riff $ git config --global pager.show riff ... then all future 'git diff's and 'git show's will be refined.

An easy to use, high-performance, flexible and extensible metadata transformation system, focused on library-archives-museums input, and indexing to Solr as output.

Ciphr is a CLI tool for performing and composing encoding, decoding, encryption, decryption, hashing, and other various operations on streams of data. It takes provided data, file data, or data from stdin, and executes a pipeline of functions on the data stream, writing the resulting data to stdout. It was designed primarily for use in the information security domain, mostly for quick or casual data manipulation for forensics, penetration testing, or capture-the-flag events; it likely could have other unforseen uses, but should be presumed to be an experimental toy as no effort was made to make included cryptographic functions robust against attacks (timing attacks, etc), and it is recommended not to use any included functions in any on-line security mechanisms.

A client library for Qiita API v2 written in Ruby.

Sym is a ruby library (gem) that offers both the command line interface (CLI) and a set of rich Ruby APIs, which make it rather trivial to add encryption and decryption of sensitive data to your development or deployment workflow. For additional security the private key itself can be encrypted with a user-generated password. For decryption using the key the password can be input into STDIN, or be defined by an ENV variable, or an OS-X Keychain Entry. Unlike many other existing encryption tools, Sym focuses on getting out of your way by offering a streamlined interface with password caching (if MemCached is installed and running locally) in hopes to make encryption of application secrets nearly completely transparent to the developers. Sym uses symmetric 256-bit key encryption with the AES-256-CBC cipher, same cipher as used by the US Government. For password-protecting the key Sym uses AES-128-CBC cipher. The resulting data is zlib-compressed and base64-encoded. The keys are also base64 encoded for easy copying/pasting/etc. Sym accomplishes encryption transparency by combining several convenient features: 1. Sym can read the private key from multiple source types, such as pathname, an environment variable name, a keychain entry, or CLI argument. You simply pass either of these to the -k flag — one flag that works for all source types. 2. By utilizing OS-X Keychain on a Mac, Sym offers truly secure way of storing the key on a local machine, much more secure then storing it on a file system, 3. By using a local password cache (activated with -c) via an in-memory provider such as memcached, sym invocations take advantage of password cache, and only ask for a password once per a configurable time period, 4. By using SYM_ARGS environment variable, where common flags can be saved. This is activated with sym -A, 5. By reading the key from the default key source file ~/.sym.key which requires no flags at all, 6. By utilizing the --negate option to quickly encrypt a regular file, or decrypt an encrypted file with extension .enc 7. By implementing the -t (edit) mode, that opens an encrypted file in your $EDITOR, and replaces the encrypted version upon save & exit, optionally creating a backup. 8. By offering the Sym::MagicFile ruby API to easily read encrypted files into memory. Please refer the module documentation available here: https://www.rubydoc.info/gems/sym
