The Message Digest algorithm is the hashing algorithm it is the one-way cryptographic algorithm that is used to encrypt the various length input and return fixed-length digest output to authenticate the original message, also detect the corruption or modification in original data. This can be a one-way process, you cannot reverse it to generate a source. This can be used for generating digital signatures using the hash value. The input to this tool is a block of data and the output is a fixed-size bit string of 32 bits.
This tool encrypts the credit card, debit card, or password in hash value and is stored in the database. It will match these details when original users need to verify or the hackers try to steal the details. It will detect the changes or modifications from digest messages to the user’s original message. All the eCommerce platforms use this algorithm to protect the payment and password details of customers. But this can be vulnerable if you do not follow the proper methods.
