Package: openssl Type: Package Title: Toolkit for Encryption, Signatures and Certificates Based on OpenSSL Version: 2.4.1 Authors@R: c(person("Jeroen", "Ooms", role = c("aut", "cre"), email = "jeroenooms@gmail.com", comment = c(ORCID = "0000-0002-4035-0289")), person("Oliver", "Keyes", role = "ctb")) Description: Bindings to OpenSSL libssl and libcrypto, plus custom SSH key parsers. Supports RSA, DSA and EC curves P-256, P-384, P-521, and curve25519. Cryptographic signatures can either be created and verified manually or via x509 certificates. AES can be used in cbc, ctr or gcm mode for symmetric encryption; RSA for asymmetric (public key) encryption or EC for Diffie Hellman. 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 'bignum' math methods for manually performing crypto calculations on large multibyte integers.
