Hash algorithm

Speed algorithm Description Hash size

Very fast

CRC-32

This is one of the Cyclic Redundancy Check methods, and extracts the verification code using the CRC32 polynomial, and is an algorithm mainly used to detect or verify errors that may occur after data transfer or storing.

8 Byte

Slow

MD-2

MD is an abbreviation for Message Digest, and is a message digest algorithm optimized for 8-bit computers.

16 Byte

Very fast

MD-4

Hash algorithm developed to use MD-2 algorithm on 32-bit computers

16 Byte

Very fast

MD-5

It was developed to compensate for the weakness of MD-4, and hash algorithm mainly developed for information protection, such as digital signatures and application programs.

16 Byte

Normal

SHA-1

SHA stands for Secure Hash Algorithm, and hash algorithm that converts input data of arbitrary length into output data of 160 bits in a similar way to MD-4 and MD-5 hash functions.

20 Byte

Normal

SHA-256

No matter what length value is entered, it generates a fixed result of 256 bits, and the hash algorithm that is most widely adopted and used in blockchain.

32 Byte

Normal

SHA-384

One of the algorithms designed to replace SHA-1, a hash algorithm that generates a 384-bit (48-byte) hash value.

48 Byte

Normal

SHA-512

One of the algorithms designed to replace SHA-1, a hash algorithm that generates a 512-bit (64-byte) hash value.

64 Byte

Normal

HAS-160

A cryptographic hash algorithm that converts an arbitrary input value used in the Korean certificate-based digital signature algorithm, KCDSA, into a hash value of 160 bits (20 bytes).

20 Byte
