How are passwords stored in EFT?
EFT user and administrator passwords are stored as one-way, 32-bytes PBKDF2-HMAC-SHA1 hash, with random 18-bytes salt, 1996 iterations.
Passwords stored in memory are encrypted with two-fish.
- Site-level and below: either encrypted with AES or IDs of the password physically stored in AKV
- Server-level: TwoFish
The EFT configuration files were moved to SQLite storage in EFT v22.214.171.124. Prior to v8, passwords managed by EFT for user and administrator authentication were stored using a base64-encoded SHA256* one-way hash. Passwords used for unattended operations such as outbound client transfers, database access, private key decryption, etc. must be reversible; thus, depending on the situation, these passwords are either obfuscated or encrypted (Twofish or similar) using a server-managed symmetric key. Passwords stored (temporarily) in memory are not encrypted.
