Backends

crypt supports etcd and consul as backends via the -backend flag.

Usage

usage: crypt COMMAND [arg...]

commands:
   get  retrieve the value of a key
   set  set the value of a key

Encrypted and set a value

usage: crypt set [args...] key file
  -backend="etcd": backend provider
  -endpoint="": backend url
  -keyring=".pubring.gpg": path to armored public keyring

Example:

crypt set -keyring pubring.gpg /app/config config.json 

Retrieve and decrypted a value

usage: crypt get [args...] key
  -backend="etcd": backend provider
  -endpoint="": backend url
  -secret-keyring=".secring.gpg": path to armored secret keyring

Example:

crypt get -secret-keyring secring.gpg /app/config

Support for unencrypted values

crypt set -plaintext ...
crypt get -plaintext ...

Crypt now has support for getting and setting plain unencrypted values, as a convenience. This was added to the backend libraries so it could be exposed in spf13/viper. Use the -plaintext flag to get or set a value without encryption.
