JCSP is essentially a pure-Java API (although a research alternative exists that uses the C-CSP extension to the JVM). As such, it is in principle eminently suitable for concurrency in Scala and Groovy applications as well as Java ones. JCSP can therefore provide an alternative to Scala's actor model. JCSP uses synchronised communication and ...
The CAPI/CSP architecture had its origins in the era of restrictive US government controls on the export of cryptography. Microsoft's default or "base" CSP then included with Windows was limited to 512-bit RSA public-key cryptography and 40-bit symmetric cryptography, the maximum key lengths permitted in exportable mass market software at the time.

Poly1305 is a universal hash family designed by Daniel J. Bernstein in 2002 for use in cryptography. [1] [2]As with any universal hash family, Poly1305 can be used as a one-time message authentication code to authenticate a single message using a secret key shared between sender and recipient, [3] similar to the way that a one-time pad can be used to conceal the content of a single message ...

Bouncy Castle started when two colleagues were tired of having to re-invent a set of cryptography libraries each time they changed jobs working in server-side Java SE.One of the developers was active in Java ME (J2ME at that time) development as a hobby and a design consideration was to include the greatest range of Java VMs for the library, including those on J2ME.
Fuzzy hashing, also known as similarity hashing, [1] is a technique for detecting data that is similar, but not exactly the same, as other data.This is in contrast to cryptographic hash functions, which are designed to have significantly different hashes for even minor differences.
SHA-2 basically consists of two hash algorithms: SHA-256 and SHA-512. SHA-224 is a variant of SHA-256 with different starting values and truncated output. SHA-384 and the lesser-known SHA-512/224 and SHA-512/256 are all variants of SHA-512. SHA-512 is more secure than SHA-256 and is commonly faster than SHA-256 on 64-bit machines such as AMD64.
