关于解密判断入参IsBase64的优化建议

[hnwywwh]

命名空间：VOL.Core.Extensions 类：ObjectExtension 增加方法：IsBase64String public static bool IsBase64String(this string base64String) { const int bitsEncodedPerChar = 6; int bytesExpected = (base64String.Length * bitsEncodedPerChar) >> 3; Span bytesBuffer = stackalloc byte[bytesExpected]; return Convert.TryFromBase64String(base64String, bytesBuffer, out int bytesWritten);
}

命名空间：VOL.Core.Extensions 类：SecurityEncDecryptExtensions 方法：DecryptDES 增加入参判断，优于上下文try catch if (decryptString.IsNullOrWhiteSpace()|| decryptKey.IsNullOrWhiteSpace() || !decryptString.IsBase64String()) { return decryptString; }
