SA1019: "golang.org/x/crypto/twofish" is deprecated: Twofish is a legacy cipher and should not be used for new applications. Also, this package does not and will not provide an optimized implementation. Instead, use AES (from crypto/aes, if necessary in an AEAD mode like crypto/cipher.NewGCM) or XChaCha20-Poly1305 (from golang.org/x/crypto/chacha20poly1305). (staticcheck)
