✓ use fpe::ff1::FF1;

Encrypt a numeric string using FF1 mode format-preserving encryption.

use fpe::ff1::{FF1, BinaryNumeralString}; let key = b"\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f"; let ff1 = FF1::new(&key, 10).unwrap(); let plaintext = BinaryNumeralString::from_str("1234567890").unwrap(); let ciphertext = ff1.encrypt(&[], &plaintext).unwrap();
