VapourSynth is an application for video manipulation. Or a plugin. Or a library. It’s hard to tell because it has a core library written in C++ and a Python module to allow video scripts to be created.

This library is a work in progress and is being used to research best practices. Use at your own risk.

Features:
- secp256k1 ECDSA signing/verification and key generation.
- Adding/multiplying private/public keys.
- Serialization/parsing of private keys, public keys, signatures.
- Constant time, constant memory access signing and pubkey generation.
- Derandomized DSA (via RFC6979 or with a caller provided function.)
- Very efficient implementation.

This is nss-pam-ldapd which provides a Name Service Switch (NSS) module that allows your LDAP server to provide user account, group, host name, alias, netgroup, and basically any other information that you would normally get from /etc flat files or NIS. It also provides a Pluggable Authentication Module (PAM) to do authentication to an LDAP server.

This is implemented using thin NSS and PAM modules which delegate to a dedicated service (nslcd) that queries the LDAP server with persistent connections, authentication, attribute translation, etc.
