ai3/go-common

Common code for ai3 services and tools.

A quick overview of the contents:

• client and server HTTP-based "RPC" implementation, just JSON POST requests but with retries, backoff, timeouts, tracing, etc.

• server implementation of a generic line-based protocol over a UNIX socket.

• a LDAP connection pool.

• utilities to serialize composite data types used in our LDAP database.

• a password hashing library that uses fancy advanced crypto by default but is also backwards compatible with old libc crypto.

• utilities to manage encryption keys, themselves encrypted with a password and a KDF.
