NewAesCTRStream creates a stream cipher based on AES-CTR.
NewAesDecryptionStream creates a new AES encryption stream based on given key and IV. Caller must ensure the length of key and IV is either 16, 24 or 32 bytes.
NewAesEncryptionStream creates a new AES description stream based on given key and IV. Caller must ensure the length of key and IV is either 16, 24 or 32 bytes.
NewAesGcm creates a AEAD cipher based on AES-GCM.
func NewAesStreamMethod(key []byte, iv []byte, f func(cipher.Block, []byte) cipher.Stream) cipher.Stream
NewChaCha20Stream creates a new Chacha20 encryption/descryption stream based on give key and IV. Caller must ensure the length of key is 32 bytes, and length of IV is either 8 or 12 bytes.
