Cryptographic hash functions are intended to resist collision finding and thus your algorithm would weaken the hash function so much that it would loose its credibility. This is what happened to several former hash functions such MD-1,MD-2, SHA-1,SHA-2, etc. . Cryptographic hash function is a special class of hash function that has certain properties which make it suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash) and is designed to be a one-way function, that is, a function which is infeasible to invert.

A cryptographic hash function is defined as an algorithm which runs on data to produce a value. The value is known as checksum, and the data can be a password or an individual file. These functions are used for the purpose of the verification of the authenticity of the data. …. The same hash will always result from the same data, but modifying the data by even one bit will completely change the hash. Like all computer data, hashes are large numbers, and are usually written as hexadecimal. BitCoin uses the SHA-256 hash algorithm to generate verifiably numbers in a way that requires a predictable amount of CPU

Popular Cryptographic Hash Functions MD5. Find a full list of cryptographic hashes here: Naturally, the longer the hash value, the less likely a collision will happen. For instance, a function that creates a 256-bit hash (like SHA) will have fewer collisions than one that produces a 128-bit hash (like MD5) because there are more
