Expand description

Given a secret store, a path to a secret, and a byte buffer to be decrypted, decrypt it in place. Returns a decoded structure if decryption was successful. The secret is expected to reside in a data field named “value” and is encoded as a hex string of 32 characters (16 bytes) The buffer is expected to contain both the salt and the bytes to be decrypted.
