When storing passwords, credit card numbers, or other sensitive data in databases such as the popular MySQL, MD5 hashes are commonly used with shorter strings.
What exactly is MD5?
The MD5 algorithm is a message-digest algorithm. In cryptography, it is used to compute a hash value. So, what exactly is a hash function? Simply put, a hash function takes a block of data and returns a bit string of a fixed length (hash value). The data used by hash functions is known as a “message,” and the computed hash value is known as the “message digest.”
When should you use MD5?
MD5, like other hash functions, is used in digital signatures, message authentication codes, hash table indexing, fingerprinting, detecting duplicate data, uniquely identifying files, and as checksums to detect accidental data corruption.
What is the size of an MD5 hash value?
MD5 generates a hash value of 128 bits (16 bytes). It is typically represented as a 32-digit hexadecimal number.
MD5, also known as “message-digest,” is a cryptographic hash function algorithm. This is a string of digits generated by a one-way hashing algorithm. Message digests are specially designed to protect the integrity of a piece of information or media and to identify if any part of a message has been changed or altered.
Message digests are one-way hash functions that take random-sized data and generate a fixed-length hash value.
