SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA256 Decrypt.

SHA1 Generator - calculate and check an SHA-1 hash online SHA1 was first published in 1995 and in 2001 it was described in RFC 3174 "US Secure Hash Algorithm 1 (SHA1)" [1] as an algorithm for computing a condensed representation of a message or a data file. When a message of any length less than 2^64 bits is input, for example in our SHA-1 generator, the algorithm produces a 160-bit message digest as RFC 3174 - US Secure Hash Algorithm 1 (SHA1) (RFC3174) * */ #ifndef _SHA1_H_ #define _SHA1_H_ #include /* * If you do not have the ISO standard stdint.h header file, then you * must typdef the following: * name meaning * uint32_t unsigned 32 bit integer * uint8_t unsigned 8 bit integer (i.e., unsigned char) * int_least16_t integer of >= 16 bits * */ #ifndef _SHA_enum_ #define _SHA_enum Supported Encryption Types

You could use an existing hash algorithm that produces something short, like MD5 (128 bits) or SHA1 (160). Then you can shorten that further by XORing sections of the digest with other sections. This will increase the chance of collisions, but not as bad as simply truncating the digest. Difference between MD5 and SHA1 - GeeksforGeeks Whereas SHA1 can have 160 bits length of message digest. 3. The speed of MD5 is fast in comparison of SHA1’s speed. While the speed of SHA1 is slow in comparison of MD5’s speed. 4. To make out the initial message the aggressor would want 2^128 operations whereas exploitation the MD5 algorithmic program.
