1. Configuration
    Chameleon - Chameleon is a configuration management library shipped with profile support cl-menusystem - cl-menusystem is a library for making pretty menus for controlling an application and editing the multitude of special variables which invariably exist to control an app's settings clerk - Clerk is a cron-like scheduler for tasks to execute at given intervals clinicap - clinicap is a dialect of ini file format parser and writer, implemented in Common Lisp Consfigurator - A system for declarative configuration management using Common Lisp NFiles - A library that deals with customizable path resolution, file persistence and loading persistent-variables - Persistent-variables is a convenience library that makes it easy to serialize and deserialize variables py-configparser - py-configparser allows reading and writing of configuration files stored in the Windows INI file format sawyer - TOML parser in Lisp, fully supporting version 0.4.0 trivial-configuration-parser - trivial-configuration-parser is a trivial parser library for configuration files ubiquitous - Ubiquitous is a very easy-to-use library for persistent configuration storage Universal-Config - This library tries to provide a layer for configuration files and storage that should be able to map any type of object to any configuration format and back YAML - Yet Another Markup Language:
  2. console
    Libraries for dealing with a text console/terminal:
  3. continuations
    Continuations are a way of capturing the current state of the program and packaging it for later call (see wikipedia:Continuations))
  4. convenience library
    Convenience libraries may make your code shorter to write, or may make it harder to read
  5. crane
    Crane was an ORM for Common Lisp
  6. Cryptography
    adler32 - Adler-32 is a hash algorithm like CRC-32, except that it is much faster and carries a slightly higher probability of collisions ARC4 - A Common Lisp implementation of ARC4 (trademark: RC4), a stream cipher, can be found below Blowfish - Blowfish is a 64-bit encryption algorithm, with a key length between 32 and 448 bits CL+SSL - CL+SSL is a portable interface to OpenSSL cl-cracklib - cl-cracklib is a UFFI interface to cracklib's FascistCheck function cl-crc64 - cl-crc64 implements 64 bit cyclic redundancy checks in Common Lisp CL-MD5 - CL-MD5 is a Common Lisp implementation of MD5 cl-one-time-passwords - cl-one-time-passwords implements HOTP (RFC 4226) and TOTP (RFC 6238) in Common Lisp cl-pass - cl-pass is a password hashing (via PBKDF2) and verification library cl-password-store - Password management for Common Lisp (web) applications CL-PLUS-SSL - This library is a fork of SSL-CMUCL cl-ssh-keys - Common Lisp system for generating and parsing of OpenSSH keys CL-TLS - CL-TLS is a prototype Common Lisp implementation of TLS and related protocols and standards including: CLJWT - A library for issuing and validating JSON Web Tokens CRC-32 - A library to compute the CRC-32 algorithm that is described in RFC 1952 GPGME - GPGME (GnuPG Made Easy) is a C language library that provides a high-level cryptography API for encryption, decryption, signing, signature verification and key management iescrypt - A tool to encrypt and/or sign files Ironclad - Ironclad is a Common Lisp Cryptography package; several block encryption algorithms and hash functions are included with the initial release isaac - An implementation of the isaac CPRNG in Common Lisp md5 - md5 is a cryptographic Message-Digest algorithm from RSA Data Security, Inc PRBS - Library of pseudo-random binary sequence generators (LFSR-2 and LFSR-4) and related functions in Common Lisp random-state - This is a collection of pseudo random number generators (PRNGs) SAFER - SAFER (Secure And Fast Encryption Routine) is a block cipher that was first published in 1993, followed by later variants secure-random - secure-random provides a cryptographically secure pseudo-random number generator for Common Lisp session-token - session-token is a simple session token generator based on Session::Token SHA1 - Secure Hash Algorithm 1 (SHA1) is defined in RFC 3174, and therefore more-or-less counts as a protocol sha3 - This library is an implementation of the Secure Hash Algorithm 3 (SHA-3), also known as Keccak SSL-CMUCL - SSL-CMUCL is an interface to SSL streams for CMUCL XXTEA - XXTEA is an encryption algorithm, first introduced in 1998, which is relatively easy to implement Ystok-MD5 - Ystok-MD5 is a Cryptography library implementing MD5 and MD5 APR (Apache Portable Runtime)
