##Pubkeytool

Pubkeytool (pkt) is a simple, lightweight commandline-tool for verification and encryption using asymmetric keys (public/private keypairs). It supports RSA, ECC and DSA. It also has some utility-commands for hashing and BASE64-(de)coding. Pubkeytool was written for use on minimalistic hardware, such as embedded systems, for which OpenSSL is too heavy. Currently, pkt uses LibTomCrypt, as it has a sufficiently small footprint and an unrescrictive license. However, it can easily be modified or extended to use another backend.
