Search Results for "entropy"

...Instead of scanning only a limited set of repositories, the tool leverages GitHub’s Code Search API to analyze results from across the entire public GitHub ecosystem, including repositories and Gists. GitHound examines files returned by search queries and applies detection methods such as regex pattern matching, entropy analysis, and contextual evaluation to identify likely credentials. It can also dig into commit history to uncover secrets that may have been removed or reverted but still exist in older revisions. This capability makes it useful for security researchers, DevSecOps teams, and bug bounty hunters who need to detect leaked credentials.

Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. ...

A console script to provide functionality similar to ubuntu pollinate and gather entropy from online sources to increase quality of randomness available to applications.
