AES-GCM recommended

Provides encryption and authentication. Use a unique IV for every encryption with the same key.

PBKDF2 SHA-256 derives an AES key from your passphrase and a random salt.

Sensitive input and keys are never written to the application log. Browser crypto is preferred when available.
