This is why GUIDs should not be used in cryptography, e.g., as random keys. (from en.wikipedia.org/wiki/Globally_Unique_Identifier)

Thus, the term ‘pseudo’ random number generators. The algorithms essentially generate numbers that, while not being truly random, are random enough for cryptographic applications.

WebBLS digital signature. A BLS digital signature —also known as Boneh–Lynn–Shacham [1] (BLS)—is a cryptographic signature scheme which allows a user to verify that a signer is authentic. The scheme uses a bilinear pairing for verification, and signatures are elements of an elliptic curve group. WebRSA (Rivest-Shamir-Adleman) is an algorithm used by modern computers to encrypt and decrypt messages. It is an asymmetric cryptographic algorithm. Asymmetric means that there are two different keys. This is also called public key cryptography, because one of the keys can be given to anyone.
