BEDBUG

A family of FLEA-inspired CSPRNGs and Stream Ciphers, BEDBUG is a small, fast, cryptographically secure pseudo-random number generator. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

AUM

A minimal CSPRNG reflecting the Zen of cipher design. AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

OAuth2Client

An RFC 6749 OAuth2 Client implemented as a Lazarus Package. The client is intended to be fully featured and supports the following grant types: Authorization Code Grant Implicit Grant Resource Owner Password Credentials Grant Client Credentials Grant. Attention has also been paid to extensibility. The client also provides: A means of implementing an Extension Grant, including new grant types. Support for new token types Support for New Endpoint Parameters, and Support for additional error codes. This OAuth2 Client uses an external User Agent - the System Web Browser - and incorporates in internal http server for handling redirect responses from an Authorization Server. The package uses the Indy Component library for both an http/https client and an http server. When the https protocol is used the OpenSSL library must also be installed and available for use. Multithreading support is required for Authorization Code and Implicit Grants. The package is written in Object Pascal and is made available under the Lesser GPL. The package requires the Indy package for http/https protocol support. It has been configured for use with the MWA Software IndySecOpenSSL package and the Indy Component Library. A separate branch (Indy106Compat) is also available. This will work with the Indy Component library on its own. However, you will be limited to using the unsupported OpenSSL 1.0.2 library (current is OpenSSL 3.x) and TLS 1.2. For installation instructions please refer to the User Guide.
