- recursive type — A data type which contains itself. The commonest example is the list type, in Haskell: data List a = Nil | Cons a (List a) which says a list of a's is either an empty list or a cons cell containing an 'a' (the "head" of the list) and another list (the "tail"). Recursion is not allowed in Miranda or Haskell synonym types, so the following Haskell types are illegal: type Bad = (Int, Bad) type Evil = Bool -> Evil whereas the seeminly equivalent algebraic data types are acceptable:

- rsa encryption — (cryptography, algorithm) A public-key cryptosystem for both encryption and authentication, invented in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. Its name comes from their initials. The RSA algorithm works as follows. Take two large prime numbers, p and q, and find their product n = pq; n is called the modulus. Choose a number, e, less than n and relatively prime to (p-1)(q-1), and find its reciprocal mod (p-1)(q-1), and call this d. Thus ed = 1 mod (p-1)(q-1); e and d are called the public and private exponents, respectively. The public key is the pair (n, e); the private key is d. The factors p and q must be kept secret, or destroyed. It is difficult (presumably) to obtain the private key d from the public key (n, e). If one could factor n into p and q, however, then one could obtain the private key d. Thus the entire security of RSA depends on the difficulty of factoring; an easy method for factoring products of large prime numbers would break RSA.
