Jervis's Salt for PBKDF2 derived from password
Vulnerability
The salt is derived from sha256Sum(passphrase). Two encryption operations with the same password will have the same derived key.
Impact
Pre-computation attacks.
Severity is considered low for internal uses of this library and high for consumers of this library.
Patches
Jervis will generate a random salt for each password and store it alongside the ciphertext.
Upgrade to Jervis 2.2.
Workarounds
None
