@pst: I took in account some of the existing hash functions that give a 64 bit output, but for example the crc64 needs far more than 100 bytes of ram. As I stated in the question, the goal is to obtain a message digest, so a cryptographic function would be better.

7 Aug 2019 In Cryptography, SHA is cryptographic hash function which takes input as 20 Bytes and rendered the hash value in hexadecimal number,

It also exists in a number of variants, all of which have been released into the public domain. The name comes from two basic operations In cryptography, SHA-1 (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 digits long. To obtain hash values of other bit lengths than 32 or 64, the simplest way is to use bitwise AND to extract bits from the the 64-bit hash value calculated by the fast-hash. Another more robust technique suggested by Knuth in his masterpiece "The Art of Computer Programming Vol2" follows: $ ./botan speed --msec=3000 --cpu-clock-speed=3400 SHA-1 SHA-224 SHA-256 SHA-384 SHA-512 MD5 hash buffer size 1024 bytes: 236.689 MiB/sec 13.70 cycles/byte (710.07 MiB in 3000.00 ms) SHA-160 hash buffer size 1024 bytes: 355.444 MiB/sec 9.12 cycles/byte (1066.33 MiB in 3000.00 ms) SHA-224 hash buffer size 1024 bytes: 250.667 MiB/sec 12.94 cycles Rex I'm sure you are aware of this, but as @AdamRobinson noted, no hash (including .NET cryptographic hashes such as SHA1) can ensure uniqueness; Not as long as the hash is a many-to-one mapping i.e. if there are fewer possible hashcodes than possible inputs. – Spike0xff Jan 8 '13 at 14:51 The MD5 Message-Digest Algorithm is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value.

I can easily convert it to a byte array, but unsure how to proceed from there. Are there any classes in the .NET framework that can assist me, or is anyone aware of some efficient algorithms to create such a unique Hello! I want to take a moment to share the story behind why I started Bit Byte Hash and the principles in which we live by.. I grew up in a small rural town of East Tennessee, Bristol to be exact, in a time where personal computers and the Internet were just coming into existence for the common American household.
