branca

Branca is a secure alternative to JWT, This implementation is written in pure Go (no cgo dependencies) and implements the branca token specification.

It was originally forked from github.com/hako/branca and the API and implementation fairly extensively modified. Specifically:

• the token payload is now []byte not string.
• the client is responsible for checking timestamp expiry, which simplifies the API and makes it possible to use a different expiry duration based on the payload contents.
• it's possible for external code to choose the nonce and timestamp, which is useful for tests.
• the external basex dependency has been removed.
• encoding a token no longer returns an error.
• the base62 wrapping is now optional, making it efficient to fold a token into some other binary format without incurring double-encoding cost.
• less work is done for each encoding and decoding (the encrypter and the base62 encoder are created only once)

Requirements

Go 1.10 and beyond.
