MD5 Hash Generator
Use this generator to create an MD5 hash of a string:
What is an MD5 Hash?
An MD5 hash is a cryptographic one-way hash function, or digital fingerprint, of an arbitrary length string that produces a 128-bit output value. The important point to be aware of regarding an MD5 hash is that, for the same input, regardless of the number of times you apply the hash to it, the output will be the same. It would be useful for all data-integrity-based operations. An example is that a developer will use MD5 hash generators to ensure the password and sensitive data remain intact while stored and when transmitting.

The MD5 Hash Generator is an important tool for developers who work with databases such as MySQL. It is sad that in spite of the cryptographic unsafeness of MD5, it is still a favorite among many due to its simplicity and ease of use. In fact, it became very popular among a great number of PHP and ASP programmers who wished to get at least a very basic protection against data integrity problems and an easy way to mask sensitive information on their Web sites.
MD5 Hash: Not Encryption, But Essential
Remember, a MD5 hash isn’t encryption. The MD5 hashing process is a one-way process, quite unlike encryption, which happens to encode data and then decode it later. After a string has been converted to an MD5 hash, it is next to impossible to reverse-engineer the hash back to the original string. This alone makes it ideal for safely storing data.
Restrictions of MD5 Hashes
Although the MD5 Hash Generator utility is very helpful in most uses, we must note that the MD5 hash algorithm is by no means secure in cryptographic operations nowadays. Technological advances are already enabling the weaknesses in the MD5 algorithm to be exploited, so that it is possible to forge collisions, situations where different inputs will create the same hash. Because of this, MD5 should not be used for high-security implementations like SSL certificates or digital signatures.
