Different versions of Windows use different implementations. ANSI X9.17 standard (Financial Institution Key Management (wholesale)), which has been adopted as a FIPS standard as well. It takes as input a TDEA (keying option 2) key bundle k and (the initial value of) a 64-bit random seed s. Each time a random number is required it:
The first has one 32-bit word of state, and period 2 32 −1. The second has one 64-bit word of state and period 2 64 −1. The last one has four 32-bit words of state, and period 2 128 −1. The 128-bit algorithm passes the diehard tests. However, it fails the MatrixRank and LinearComp tests of the BigCrush test suite from the TestU01 framework.
RDRAND (for "read random") is an instruction for returning random numbers from an Intel on-chip hardware random number generator which has been seeded by an on-chip entropy source. [1] It is also known as Intel Secure Key Technology, [2] codenamed Bull Mountain. [3] Intel introduced the feature around 2012, and AMD added support for the ...
Softland's doPDF is a freeware application that is licensed for commercial and personal use. It supports 32-bit and 64-bit Windows 11, Windows 10, Windows 8, Windows 7, Vista, 2019, 2016, 2012 and 2008 R2. Earlier versions up until version 9 also supported XP, Windows Server 2000, 2003, and 2008 operating systems.
ChaCha20-Poly1305 is an authenticated encryption with additional data (AEAD) algorithm, that combines the ChaCha20 stream cipher with the Poly1305 message authentication code. Its usage in IETF protocols is standardized in RFC 8439. [1] It has fast software performance, and without hardware acceleration, is usually faster than AES-GCM.
TCPDF is a free and open source software PHP class for generating PDF documents. TCPDF is the only PHP-based library that includes complete support for UTF-8 Unicode and right-to-left languages, including the bidirectional algorithm. [2] In 2009 TCPDF was one of the most active of over 200,000 projects hosted on SourceForge (best ranked 6th on ...
Comparison of implementations of message authentication code (MAC) algorithms. A MAC is a short piece of information used to authenticate a message—in other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed in transit (its integrity). Implementation. HMAC - MD5.
NIST SP 800-90A ("SP" stands for " special publication ") is a publication by the National Institute of Standards and Technology with the title Recommendation for Random Number Generation Using Deterministic Random Bit Generators. The publication contains the specification for three allegedly cryptographically secure pseudorandom number ...
