MD5 is the most common cryptographic algorithm used in Web applications. Since the MD5 is irreversible, the ciphertext after MD5 calculation can not get the original text through the reverse algorithm. The intention of using MD5 encrypted text passwords in Web applications is to prevent the passwords stored in the database from being compromised and then being directly acquired. However, the attackers not only have a large number of password dictionaries, but also set up a lot of MD5 original/ciphertext control database, can quickly find common password MD5 ciphertext, is the efficient way to decipher MD5 ciphertext. However, the number of MD5 ciphertext ...

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...
