Instance Method Summary

• #decrypt(src, dst : Bytes? = nil, *, nonce : Nonce, additional = nil) : Bytes

  Decrypts src and returns plaintext Must supply nonce Must supply additional if supplied to #encrypt

• #decrypt_detached(src, dst : Bytes? = nil, *, nonce = nil, mac : Bytes? = nil, additional = nil) : Bytes

  Decrypts src and returns plaintext Must supply mac and nonce Must supply additional if supplied to #encrypt

• #decrypt_detached(src : Bytes, dst : Bytes? = nil, *, nonce : Sodium::Nonce, mac : Bytes, additional : String | Bytes | Nil = nil) : Bytes
• #decrypt_detached_string(src, dst : Bytes? = nil, *, nonce = nil, mac : Bytes? = nil, additional = nil) : String
