Hashing is a one-way process that generates a fixed-length string of characters or digits from input data, such as a password, a message, or a file. The length of SHA1 and MD5 hashes are fixed (20 bytes for SHA1 and 16 bytes for MD5)īase64 encoding is used to represent binary data in an ASCII string format, allowing it to be easily transmitted over text-based systems, such as email or HTML. The length of a Base64 encoded string varies. What is the main difference between base64 encoding and hashing (SHA1, MD5)? Unlike MD5 and SHA1, you can decode the Base64 encoded text with the base64 decoder and decode the image from the Base64 encoded string with the base64 image decoder. These 6 bits reveal the character supported by the characters set in the base 64 scheme. These three bytes (24 bits) are further broken into four packs of six bits each. In Base64, the data are broken down into 24 bits (three bytes). The encoding scheme uses the 64 characters set that are present in the majority of the character sets. Base64 Encodingīase64 is a binary to ASCII encoding scheme that stores and transfers the binary data over medium, supporting only textual data. The drawback is that MD5 is already cracked, and it is recommended to refrain from using it with sensitive data like banking or e-commerce. So, how can we ensure the accuracy of the 32 digits digests being converted to 750,000 characters? That's the reason MD5 does not have a reversible function. But the final output is 32 digits digest. Suppose we use the MD5 algorithm on text data of about 750,000 characters. It takes the data of any size as input and gives you a fixed size 128 bits (16 bytes) output. MD5 follows the same rules as the hash algorithm. It inputs the data block and returns the fixed-size bit string as a hash value. The primary function of MD5 is to calculate the hash value in cryptography. Ronald Rivest invented that cryptographic function in 1991. MD5 stands for Message-Digest Algorithm 5. Undoubtedly, the SHA1 algorithm is complex, but the significant part is that it is not used anymore because it has been cracked and is considered unsafe. That process continues for "n" times until the last 160 bits of the message are produced. We have a pre-set value for the 160 bits for the first time we carry this out. These 512 bits are then brought in the compression function and the 160 bits of compressed output. SHA is generated by breaking our input content into the "n'' number of parts that we represent as X, each of 448 bits, and adding 64 bits of padding to each, converting their total length to 512 bits. SHA1 hash is an algorithm that generates the 160 bits' hash value. Act as checksums in detecting accidental data corruption.To sort and identify files to ensure the data integrity of the files.In creating digital signatures and message verification codes.To keep the credit card numbers and other essential data in databases.Generate passwords to store them for later use in the authentication of users in databases.The two different contents cannot have the same message digest.The original content is not derivable from the hash value or message digest.So, there are two required rules that each hash function must follow. That means the hash functions' output is of fixed length and can alter depending upon the hash function you use, but the hash's length would not change for a specific hash function. Moving the same content through the same hash function should produce the same output or hash value.We cannot reverse a hash value to recover the original content, which means it is irreversible. The string is the hash value, message digest, digital fingerprint, digest, or checksum. Hashing is a cryptographic function that takes an input of variable length and returns a fixed-size alphanumeric string. Many applications or technologies use that technique to avoid security breaches and for faster search results.
