如何在golang中用SHA1PRNG算法生成aes？

import (
    "crypto/aes"
    "crypto/cipher"
    "crypto/rand"
    "crypto/sha1"
    "io"
)

func generateAESKey(password string, salt []byte) []byte {
    sha1Hash := sha1.New()
    sha1Hash.Write([]byte(password))
    sha1Hash.Write(salt)
    key := sha1Hash.Sum(nil)
    return key[:16] // AES-128使用16字节密钥
}

func encrypt(plainText []byte, key []byte) ([]byte, error) {
    block, err := aes.NewCipher(key)
    if err != nil {
        return nil, err
    }

    cipherText := make([]byte, aes.BlockSize+len(plainText))
    iv := cipherText[:aes.BlockSize]
    if _, err := io.ReadFull(rand.Reader, iv); err != nil {
        return nil, err
    }

    stream := cipher.NewCTR(block, iv)
    stream.XORKeyStream(cipherText[aes.BlockSize:], plainText)

    return cipherText, nil
}

func decrypt(cipherText []byte, key []byte) ([]byte, error) {
    block, err := aes.NewCipher(key)
    if err != nil {
        return nil, err
    }

    iv := cipherText[:aes.BlockSize]
    cipherText = cipherText[aes.BlockSize:]

    stream := cipher.NewCTR(block, iv)
    stream.XORKeyStream(cipherText, cipherText)

    return cipherText, nil
}

func main() {
    password := "myPassword"
    salt := []byte("mySalt")

    key := generateAESKey(password, salt)

    plainText := []byte("Hello, World!")

    cipherText, err := encrypt(plainText, key)
    if err != nil {
        panic(err)
    }

    decryptedText, err := decrypt(cipherText, key)
    if err != nil {
        panic(err)
    }

    fmt.Println("Decrypted Text:", string(decryptedText))
}
