Vowpal wabbit has been used to learn a tera-feature (10 12) data-set on 1000 nodes in one hour. [1] Its scalability is aided by several factors: Out-of-core online learning: no need to load all data into memory; The hashing trick: feature identities are converted to a weight index via a hash (uses 32-bit MurmurHash3)
NiceHash is a cryptocurrency broker and exchange with an open marketplace for buyers and sellers of hashing power. The company provides software for cryptocurrency mining.The company was founded in 2014 by two Slovenian university students, Marko Kobal and Matjaž Škorjanc. [1]
The proof-of-work distributed computing schemes, including Bitcoin, frequently use cryptographic hashes as a proof-of-work algorithm. Hashrate is a measure of the total computational power of all participating nodes expressed in units of hash calculations per second.
Robert John Jenkins Junior (born 1966 [1] in Akron, Ohio), also known as Bob Jenkins, is an American computer professional and author of several fast pseudorandom number generators such as ISAAC [2] [3] [4] and hash functions (Jenkins hash) [5] [6]
BLAKE repeatedly combines an 8-word hash value with 16 message words, truncating the ChaCha result to obtain the next hash value. BLAKE-256 and BLAKE-224 use 32-bit words and produce digest sizes of 256 bits and 224 bits, respectively, while BLAKE-512 and BLAKE-384 use 64-bit words and produce digest sizes of 512 bits and 384 bits, respectively.
Examples of hashcat-supported hashing algorithms are LM hashes, MD4, MD5, SHA-family and Unix Crypt formats as well as algorithms used in MySQL and Cisco PIX. Hashcat has received publicity because it is partly based on flaws in other software discovered by the creator of hashcat. An example was a flaw in 1Password's password manager hashing ...

The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form: $2<a/b/x/y>$[cost]$[22 character salt][31 character hash] For example, with input password abc123xyz, cost 12, and a random salt, the output of bcrypt is the string
