     "This package provides R bindings to OpenSSL libssl and libcrypto, plus
custom SSH pubkey parsers.  It supports RSA, DSA and NIST curves P-256, P-384
and P-521.  Cryptographic signatures can either be created and verified
manually or via x509 certificates.  AES block cipher is used in CBC mode for
symmetric encryption; RSA for asymmetric (public key) encryption.  High-level
envelope functions combine RSA and AES for encrypting arbitrary sized data.
Other utilities include key generators, hash functions (md5, sha1, sha256,
etc), base64 encoder, a secure random number generator, and @code{bignum} math
methods for manually performing crypto calculations on large multibyte
integers.")

     "This package provides an exact Goodness-of-Fit test for
multinomial data with fixed probabilities.  It can be used to
determine whether a set of counts fits a given expected ratio.  To see
whether a set of observed counts fits an expectation, one can examine
all possible outcomes with @code{xmulti()} or a random sample of them
with @code{xmonte()} and find the probability of an observation
deviating from the expectation by at least as much as the observed.
As a measure of deviation from the expected, one can use the
log-likelihood ratio, the multinomial probability, or the classic
chi-square statistic.  A histogram of the test statistic can also be
plotted and compared with the asymptotic curve.")
