Open Source BSD Command Line Tools

ccrypt is a command-line tool for encrypting and decrypting files and streams. It provides strong encryption based on the Rijndael cipher, a version of which is also used in the Advanced Encryption Standard.

testssl.sh is a free command-line tool that checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. testssl.sh is free and open-source software. You can use it under the terms of GPLv2, please review the License before using it. Works for Linux, Mac OSX, FreeBSD, NetBSD and WSL/MSYS2/Cygwin out of the box, no need to install or configure something, no gems, CPAN, pip or the like. OpenBSD only needs bash to be postinstalled. You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443. Several command line options help you to run your test and configure your output. If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning. You can look at the code, see what's going on and you can change it.

FEHASHMAC is the largest collection of publicly known hash algorithms integrated into a command-line utility. FEHASHMAC contains a set of known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can directly be verified. Currently 57 hash algorithms like sha1 sha224 sha256 sha384 sha512 and variants, sha3 and shake, all SHA3 finalists and blake3, md2 md4 md5 md6, rmd128 rmd160 rmd256 rmd320, whirl gost lash160 lash256 lash384 lash512 tiger2 and RFC 2104 HMAC and KMAC support are included, plus SHA3 extensions kmac128, kmac256, kmacxof128, kmacxof256 for message.

BBSGen is an improved Blum-Blum-Shub pseudorandom number generator. It consists of a C library (libbbsgen) and command-line tool (bbsgen). BBSGen can be used in applications and command-line as secure, unpredictable and strong PRNG.

NOAHDB is a command line tool that parses the log files that are emitted by the Argos Honeypot and populates the tables of a MySQL database.

Small cryptographic command line tool for LINUX and OpenBSD (x86) completely in 32-Bit Assembly Language. ORDO encrypt/decrypt files (max. size 2 GB) with AES-128-Algorithm (Rijndael) in CBC-Mode (Cipher-Block-Chaining). No libs are included, only system-calls are used. ORDO is under BSD License.

SimpleDriveWiper is a very simple command line tool that allows you to wipe the free space of a drive/partition. Its purpose is to obfuscate the residual of data that remains even after attempts have been made to remove it. For Windows,Linux and Mac.

A command line tool to create secure encrypted file using private key. You must provide key string to convert you source file into ecrypted one.
