What is a MD5?

How is Message-Digest Algorithm 5 defined?

MD5 is a cryptographic hash function algorithm also known as "Message-Digest Algorithm 5". This string contains a series of digits generated by a unique one-way hashing procedure. Message-Digests Or MD5 are specially designed to safeguard the integrity of a piece of information, credential, data or media and to identify if there are changes and alterations to any part of a message itself.

MD5 can produce a 128-bit (16 bytes) hash value, and it is characterized by a hexadecimal number of 32 digits.

Message-Digests are protected one-way hash functions that take random-sized data and produce a fixed-length hash value.

What is a MD5 used for?

How Message-Digest Algorithm 5 work?

The main function of MD5 is to calculate a hash value in cryptography. While the hash function is to get blocks of data and return them with a fixed-size bit string or hash value. The data that has been utilized by hash functions is referred to as a "message"; while, the calculated hash value is "message digest".

MD5 remains useful for compatibility and accidental-error checks, such as comparing a downloaded file with a checksum published by its provider. Do not use it where collision resistance is required, for digital signatures, passwords, or new security systems.

The same input produces the same digest, but two different inputs can collide. For modern uses requiring collision resistance, prefer SHA-256 or another SHA-2 function.

A hash is not encryption and Base64 is not a hash: neither protects a secret. Password storage requires dedicated slow password-hashing functions with salts and suitable parameters.

What is a SHA-1 encoding?

How does SHA-1 encoding work?

SHA stands for Secure Hash Algorithm. SHA-1 and SHA-2 are distinct families: SHA-1 is deprecated where collision resistance is required, while SHA-256, SHA-384, and SHA-512 belong to SHA-2.

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 known as a Message Digest, typically rendered as a hexadecimal number, 40 chaotic digits long.

SHA-1 is most often used to verify that a file has been unaltered. This is done by producing a checksum before the file has been transmitted, and then again once it reaches its destination.

When learning about SHA forms, several different types of SHA are referenced. SHA-2 can produce a variety of bit-lengths, from 256 to 512 bit, allowing it to assign completely unique values to every hash digest created. Examples of SHA are SHA-1, SHA-2, SHA-256, SHA-512, SHA-224, and SHA-384, but in actuality there are only two types: SHA-1 and SHA-2. The other larger numbers are just versions of SHA-2 that note the bit lengths of the SHA-2.

What is a Base64 encoding?

How does Base64 encoding work?

Base64 is a group of binary-to-text encoding schemes that represent binary data (a sequence of 8-bit bytes) in an ASCII string format by translating the data into a radix-64 representation.

Common to all binary-to-text encoding schemes, Base64 is designed to carry data stored in binary formats across channels that only reliably support text content. Some media are made for streaming text. You never know, some protocols may interpret your binary data as control characters, or your binary data could be screwed up because the underlying protocol might think that you've entered a special character combination. So to get around this, developers encode the binary data into characters. Base64 is one of these types of encodings, you can generally rely on the same 64 characters being present in many character sets, and you can be reasonably confident that your data's going to end up on the other side of the wire uncorrupted.

Base64 encoding is not a way of encrypting, nor a way of compacting data. In fact a Base64 encoded piece of data is 1.333... times bigger than the original data piece. It is only a way to be sure that no data is lost or modified during the transfer.
