Read Catalogue First, Base64 code Second, MD5, SHA1, SHA256, SHA512, HMAC implementation GitHub Code It is said that today 520 is a good day, why I think of 502, 500, 404 these? Fortunately the server is OK!First, Base64

The commonly used message digest algorithms are MD5 and SHA, which are available in both Python and go libraries, and are OK when called, which summarizes the implementation of Python and went. Example of a Python message digest The code is as

Commonly used message digest algorithm has MD5 and SHA, these algorithms in the Python and go library have, need time to call under OK, here summarizes the implementation of Python and go. Example of a Python message digest The code is as

The zero-based NODEJS series article will show you how to benefit JavaScript as a server-side script through NODEJS Framework web development. The NODEJS framework is a V8-based engine and is the fastest JavaScript engine available today. The Chrome

Symmetric encryption tool, understanding the principle of symmetric encryption is very simple, the principle section is shown below. OpenSSL enc-ciphername [-in filename] [-out filename] [-pass arg] [-e] [-d] [-a/-base64] [-k password] [-S SALT]

Previous wordsCryptographic modules provide a way to encapsulate security credentials during an HTTP or HTTPS connection. It also provides encapsulation of OpenSSL's hash, HMAC, encryption (cipher), decryption (decipher), signature (sign), and
