Buddy - Security library for clojure.

Clojars Project

this project is deprecated and not going to be updated; plase use the individual modules: buddy-core, buddy-auth, buddy-sign and buddy-hashers.


buddy is a complete security library for clojure. With support for:

  • authentication, authorization & access rules (ring/compojure extensions)

  • secure hash functions (digest)

  • password hashing algorithms (bcrypt, pbkdf2, scrypt)

  • message/text signing (high level interface)

  • signature & authentication (mac & digital signature)

  • encryption (block, stream ciphers, nonces, salts)

  • key derivation functions (kdf)

Since version 0.3.0, buddy is split into four modules for improved modularity of the application and to allow people to include only wanted parts of buddy instead of one monolithic library.

Each module has its own functionality and its own documentation. This document/page only serves as an introduction to the library and the content of index.

If you are happy with the monolithic version of buddy, you may want include the "buddy" meta-package:

[buddy "2.0.0"]

In other case, see the concrete installation instructions of the module that you need.
