请教 go 标准库 aes 的默认的加密模式是什么?没有 openSSL 里的那种初始化变量 IV,是有个默认值?还是说 go 标准库里默认的初始化 iv=key ?

目测代码有问题 我的代码是这样的 ``` go //AESEncrypt aes encrypt with given data,key and iv. //Data will be padding with PKCS7Padding //Return encrytped data and any error if raised. func AESEncrypt(unencrypted []byte, key []byte, iv []byte) (encrypted []byte, err error) { defer func() { r := recover() if r != nil { err = r.(error) } }() cryptKey := formatKey(key, aes.BlockSize) block, err := aes.NewCipher(cryptKey) if err != nil { return } data := PKCS7Padding(unencrypted, aes.BlockSize) crypter := cipher.NewCBCEncrypter(block, iv) encrypted = make([]byte, len(data)) crypter.CryptBlocks(encrypted, data) return } // AESNonceEncrypt aes encrypt data with given key and random bytes as IV. //Data will be padding with PKCS7Padding //Random IV will prefix encryped data //return encrypted data and any error if raisd. func AESNonceEncrypt(unencrypted []byte, key []byte) (encrypted []byte, err error) { defer func() { r := recover() if r != nil { err = r.(error) } }() var rawEncrypted []byte var IV = make([]byte, IVSize) _, err = rand.Read(IV) if err != nil { return } rawEncrypted, err = AESEncrypt(unencrypted, key, IV) if err != nil { return } encrypted = make([]byte, len(rawEncrypted)+int(IVSize)) copy(encrypted[:IVSize], IV) copy(encrypted[IVSize:], rawEncrypted) return } ```

你好
你给的代码是 ECB 模式的,ECB模式是没有IV的。 具体的可以看这个 https://github.com/deatil/go-cryptobin/blob/main/cryptobin/encryption_cipher.go#L45

没有默认的,你用什么就是什么
