HOW TO ENCRYPT YOUR POST

Encryption is the process of securing the information by making such information can not be read without the aid of specialized knowledge.
The advantage of encryption is the original code we can not be read by others.
Here are some kinds of encryption methods can be used on web programming like PHP, ASP and others.

1. Encryption Method MD2
Message-Digest algortihm 2 (MD2) is a cryptographic hash function developed by Ronald Rivest in 1989.
The algorithm is optimized for 8-bit computer. MD2 specified in RFC 1319.
Although other algorithms have been proposed since the first, such as MD4, MD5 and SHA, even up to 2004 [update] MD2 still used in public key infrastructures as part of a certificate generated with MD2 and the RSA.

2. Encryption Method MD4
Message-Digest algortihm 4 (4th series) designed by Professor Ronald Rivest of MIT in 1990.
Its length is 128 bits.
MD4 was also used to calculate summary NT-hash password in Microsoft Windows NT, XP and Vista.

3. MD5 Encryption Method
MD5 is one of a series of message digest algorithms designed by Professor Ronald Rivest of MIT (Rivest, 1994).
When analytic work indicated that MD5's predecessor namely MD4 start insecure, MD5 then designed in 1991 as the successor of MD4 (MD4 weakness was discovered by Hans Dobbertin).
In cryptography, MD5 (Message-Digest algortihm 5) is a cryptographic hash function widely used with 128-bit hash value.
In Internet standard (RFC 1321), MD5 has been utilized in a variety of security applications, and MD5 are also commonly used for testing the integrity of a file.

4. SHA Encryption Method
SHA is a series of cryptographic hash functions designed by the National Security Agency (NSA) and published by NIST as a U.S. Federal Information Processing Standard.
SHA is the Secure Hash Algorithm. The types of SHA SHA-0, SHA-1, and SHA-2.
For SHA-2 using an algorithm that is identical to the summary measures of variables known as SHA-224, SHA-256, SHA-384, and SHA-512.

5. RC4 Encryption Method
RC4 is one type of stream cipher, namely processing units or input data at one time. Unit or a byte of data in general or sometimes even a bit (byte in the case of RC4).
In this way the encryption or decryption can be performed on the length of the variable.
RC4 is a stream cipher encryption made by Ron Riverst in 1987 for RSA Security.
Algorithm based on random permutations.

6. Base64 Encryption Method
Base64 is a system to represent the raw data byte as ASCII characters.
Base64 provides 6-bit encoding 8-bit ASCII characters.
Base64 is a format that is printed using characters, allowing binary data to be sent in the form and email, and will be stored in a database or file.
