Crypt

Filter Crypt

Overview

This filter encrypts or decrypts a field and writes the resulting value to another (or the same) field.

Supported algorithms:

• fernet

Fernet configuration

• Key: 256-bit key used to encrypt/decrypt the token.
• TTL: optional duration (in seconds). When set, the key must have been signed at most TTL ago, or decryption will fail. Only applicable for decryption.

Configuration

Keys available in the [filter.config] section:

Name	Type	Default	Required	Description
Algorithm	string	""	true	Name of the algorithm to use for crypting/decrypting
Decrypt	bool	false	false	True for decrypting, false for encrypting
SrcField	string	""	true	Name of the field to crypt/decrypt
DstField	string	""	true	Name of the field to write the result to
AlgorithmConfig	map of strings to strings		false	AlgorithmConf contains configurations required by the chosen algorithm
