sqlx 加密列 key长度校验

[hookokoko]

go中gcm加密算法中的仅支持16、24、32的key，在加密列工具中是否应该增加下对key的校验？将错误包装一下提示给用户

这是aes中的NewCipher方法

// NewCipher creates and returns a new cipher.Block.
// The key argument should be the AES key,
// either 16, 24, or 32 bytes to select
// AES-128, AES-192, or AES-256.
func NewCipher(key []byte) (cipher.Block, error) {
	k := len(key)
	switch k {
	default:
		return nil, KeySizeError(k)
	case 16, 24, 32:
		break
	}
	if boring.Enabled {
		return boring.NewAESCipher(key)
	}
	return newCipher(key)
}
