DaveGrohl supports all of the standard Mac OS X user password hashes (MD4, SHA-512 and PBKDF2) [1] [2] [3] used since OS X Lion and also can extract them formatted for other popular password crackers like John the Ripper. [4] The latest stable release is designed specifically for Mac OS X Lion and Mountain Lion.
Mac OS X 10.4 and later support extended attributes by making use of the HFS+ filesystem Attributes File B*-tree feature which allows for named forks. Although the named forks in HFS+ support arbitrarily large amounts of data through extents, the OS support for extended attributes only supports inline attributes, limiting their size to that ...
Intrinsically keyed hash algorithms such as SipHash are also by definition MACs; they can be even faster than universal-hashing based MACs. [ 9 ] Additionally, the MAC algorithm can deliberately combine two or more cryptographic primitives, so as to maintain protection even if one of them is later found to be vulnerable.
There was a 3rd party software application developed, that enabled synchronization of personal keychains generated using keychain access in Mac OS X, these standard keychain access - generated users keychains could then be synchronised between devices (iPhones - desktop Apple computers), using a pair of keychain synchronization apps developed ...
Badger is a message authentication code (MAC) based on the idea of universal hashing and was developed [when?] by Boesgaard, Scavenius, Pedersen, Christensen, and Zenner. [1] It is constructed by strengthening the ∆-universal hash family MMH using an ϵ-almost strongly universal (ASU) hash function family after the application of ENH (see below), where the value of ϵ is / ().

This file can be protected by any combination of a master password, a key file, and the current Windows account details. By default, the KeePass database is stored on a local file system (as opposed to cloud storage). [7] KeePass comes in two different variants: KeePass 1.x and KeePass 2.x.
Several utilities, such as md5deep, can use such checksum files to automatically verify an entire directory of files in one operation. The particular hash algorithm used is often indicated by the file extension of the checksum file. The ".sha1" file extension indicates a checksum file containing 160-bit SHA-1 hashes in sha1sum format.
The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash. However, it is very unlikely that any two non-identical files in the real world will have the same MD5 hash, unless they have been specifically created to ...
