The MD5 hashing algorithm is a cryptographic algorithm that takes an input of arbitrary length and produces a message digest that is 128 bits long. The digest is sometimes also called the "hash" or "fingerprint" of the input. MD5 is used in many situations where a potentially long message needs to be processed and/or compared quickly. The most common application is the creation and verification of digital signatures.

The MD5 hashing algorithm is a one way cryptographic function tht accpts a message of any length as input and returns as output a fixed length digest value to be used for authenticating the original mssg.
SHA-1 is a cryptographic hash which takes as an input and produce a 160 bit hash value.The hash value is known as a message digest.

The MD5 hashing algorithm is a one-way cryptographic function that accepts a message of any length as input and returns as output a fixed-length digest value to be used for authenticating the original message.
SHA-1 or Secure Hash Algorithm 1 is a cryptographic hash function which takes an input and produces a 160-bit (20-byte) hash value. This hash value is known as a message digest. This message digest is usually then rendered as a hexadecimal number which is 40 digits long. It is a U.S. Federal Information Processing Standard and was designed by the United States National Security Agency.

The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. It remains suitable for other non-cryptographic purposes, for example for determining the partition for a particular key in a partitioned database

The MD5 hashing algorithm is a one-way cryptographic function that accepts a message of any length as input and returns as output a fixed-length digest value to be used for authenticating the original message.

The MD5 hash function was originally designed for use as a secure cryptographic hash algorithm for authenticating digital signatures. MD5 has been deprecated for uses other than as a non-cryptographic checksum to verify data integrity and detect unintentional data corruption.

Secure Hash Algorithm (SHA) and Message Digest (MD5) are the standard cryptographic hash function to provide data security for multimedia authentication. Cryptographic hashes play a fundamental role in modern cryptosystems. SHA and MD5 are the two well recognized hash functions. The MD5 hashing algorithm takes a message of arbitrary length as input and produces as output a 128-bit "fingerprint" or "message digest" of the input message. The SHA is a potential successor to MD5 and the algorithm specified in the Secure Hash Standard (SHS).

Secure Hash Algorithm (SHA) and Message Digest (MD5) are the standard cryptographic hash functions to provide data security for multimedia authentication. Cryptographic hashe play a fundamental role in modern cryptosystems. So it is important to understand the basic mechanism behind these algorithms and the issues involved in choosing a particular hashing algorithm. Hashing is based on a one-way mathematical function; functions that are easy to compute, but significantly tough to reverse. Hash functions are the basis of the protection mechanism of Hashed Message Authentication Codes (HMAC). It is a major enabling technology for network security used to achieve specific security objectives.

SHA and MD5 are the two well recognized hash functions. The MD5 hashing algorithm takes a message of arbitrary length as input and produces as output a 128-bit “fingerprint” or “message digest” of the input message. It is a one-way function that makes it easy to compute a hash from the given input data. It is a complex sequence of simple binary operations, such as exclusive OR (XORs) and rotations, that are performed on input data and produce a 128-bit digest. The SHA is a potential successor to MD5 and the algorithm specified in the Secure Hash Standard (SHS). SHA-1 is a revision to the SHA standard that was published in 1994. We put together an unbiased comparison between the two hashing functions.

MD5 (128 bit) and SHA1 (160 bit) are cryptographic hash functions used to encrypt information by generating a hash based on the passed byte structure. ... SHA1 is a much more secure hashing algorithm, although its principles are somewhat based on those of MD5.

MD5 hashes:
The MD5 hashing algorithm is a one-way cryptographic function that accepts a message of any length as input and returns as output a fixed-length digest value to be used for authenticating the original message.

SHA hashes:
secure hash algorithm is actually a set of algorithms developed by the National Institutes of Standards and Technology (NIST) and other government and private parties. These secure encryption or "file check" functions have arisen to meet some of the top cybersecurity challenges of the 21st century, as a number of public service groups work with federal government agencies to provide better online security standards for organizations and the public.

Secure Hash Algorithm

Secure Hash Algorithm (SHA-1) produces a 160-bit hash value from an arbitrary length string. Like MD5, it is also used widely in applications such as SSH, SSL, S-MIME (Secure / Multipurpose Internet Mail Extensions), and IPSec.

The MD5 Message-Digest Algorithm is a widely used cryptographic hash function that produces a 128 bit (16-byte) hash value. It is very simple and straight forward; the basic idea is to map data sets of variable length to data sets of a fixed length. After using MD5, generated hash is typically a 32-digit hexadecimal number .In order to do this, the input message is split into chunks of 512-bit blocks. Now these blocks are processed by the MD5 algorithm, which operates in a 128-bit state, and the result will be a 128-bit hash value.

Here, the data to be encoded is often called the “message” and the generated hash value is called the message digest “digest”.

MD5 is it is very fast, and easy to learn and implement but It generates fairly week hashes which is not too much secure. As we know storing the text password with hashing is most dangerous thing for application security today.

MD5 can be made more secure using salt: Salt is some randomly generated text, which is appended to password before obtaining hash, Like : Salt + Password + Salt = Hash.
