example itself is not perfect, does not collect attribute variables, and does not add testing (actual project does not advocate), many functional programming advanced features are not involved, not fully functional programming, follow-up will further improve the promotion. In the follow-up development of billions of books, it will also use a lot of good experience in functional programming, good practices, further compression of code, improve robustness and maintainability.All things too much,

Description
The columnar encryption scheme scrambles the letters in a message (or plaintext) using a keyword as your strated in the following example: suppose batboy is the keyword and our message is meet me by the old oak tree. since the keyword has 6 letters, we writeThe message (ignoring spacing and punctuation) in a grid with 6 columns, padding with random extra letters as needed:
MeetmeBytheoLdoachReenth
Here, we 've padded t

Use require (' crypto ') to invoke the cryptographic module.
The encryption module requires the support of the underlying system to provide OpenSSL. It provides a way to encapsulate security credentials and can be used for HTTPS secure networks and normal HTTP connections.
The module also provides a package for OpenSSL hash (hash), HMAC (key hash), cipher (encoding), decipher (decoding), sign (signature), and verify (authentication) methods.

Python Crypto module implements AES encryption instance code, cryptoaes
This article mainly explores the python Crypto module to implement AES encryption and shares the specific implementation code. The following describes the specific content.
I learned how to use the AES of the Crypto module to encrypt files. Now I can record the files for later viewing.

is often used to verify that the message is intact and not tampered with.The digest operation is irreversible. In other words, the input is fixed and produces a fixed output. However, if the output is known, the input cannot be rolled back.The pseudo code is as follows.
Digest = Hash (message)
The common summary algorithm and the corresponding output bits are as follows:
md5:128 bit
sha-1:160 bit
sha256:256 bit
sha512:512 bit

CRL file, you can view the information of the revoked certificate,. net Framework does not provide classes that can access the attributes of CRL (x509crl is provided in Java). To implement such a function, we need to use. net Framework: Bouncy castle crypto or mono SDK.
