From the aescrypt README.html:
This is a program for encrypting/decrypting streams of data using
Rijndael and Cipher Block Feedback mode (CFB-128).
...
5. This program was deliberately kept extremely simple. It is not
intended to be a full encryption solution, it is intended to be
used within scripts as part of a complete solution. Keychain
management, public key signatures, etc. are all expected to be
done external to this program.
The BlindElephant Web Application Fingerprinter attempts to discover
the version of a (known) web application by comparing static files
at known locations against precomputed hashes for versions of those
files in all available releases. The technique is fast,
low-bandwidth, non-invasive, generic, and highly automatable.
Botan is a crypto library written in C++. It provides a variety of
cryptographic algorithms, including common ones such as AES, MD5, SHA,
HMAC, RSA, Diffie-Hellman, DSA, and ECDSA, as well as many others that
are more obscure or specialized. It also offers X.509v3 certificates
and CRLs, and PKCS #10 certificate requests. A message processing
system that uses a filter/pipeline metaphor allows for many common
cryptographic tasks to be completed with just a few lines of code.
Assembly optimizations for common CPUs, including x86, x86-64, and
PowerPC, offers further speedups for critical tasks such as SHA-1
hashing and multiple precision integer operations.
Botan is licensed under the same permissive terms as FreeBSD itself.
BSDsfv is a flexible and highly compatible SFV checksum utility.
Features:
- create SFV files, verify downloaded single files or whole releases
- add banners to your SFV files
- very flexible and compatible with all other SFV tools currently known,
including SFVNIX compatibility mode concerning SFV files created
- easy to console application
- plug & play support for glFTPd and other demons including
count-missing-files feature for race scripts
Hashcat is an advanced CPU-based password recovery utility for FreeBSD,
Windows 7/8/10, Apple OS X, and GNU/Linux, supporting seven unique modes
of attack for over 100 optimized hashing algorithms.
cfv is a utility to both test and create .sfv, .csv and md5sum files. These
files are commonly used to ensure the correct retrieval or storage of data.
Features:
- supports .sfv, .csv(2, 3, and 4 field variants), md5sum, BSD md5
sha1sum, .torrent and (test-only) .par, .par2 file formats
- automatic checksum file naming ability in create mode
- recursive operation
- show unverified files option
- ignore case and fix path separator options for cross platform use
- transparent gzip support for checksum files
- configurable renaming of bad files (with testing against previous bad
files, to save only unique differing copies)
pamtester is a tiny utility program to test the pluggable authentication
modules (PAM) facility, which is a de facto standard of unified authentication
management mechanism in many unices and similar OSes including Solaris, HP-UX,
*BSD, MacOSX and Linux.
While specifically designed to help PAM module authors to test their modules,
that might also be handy for system administrators interested in building a
centralised authentication system using common standards such as NIS, SASL and
LDAP.
PWman is a console application for managing passwords. It uses
GPG (gpgme) for encryption and authentication.
The python mhash module provides an interface for the mhash library.
The mhash library provides an easy way to access strong hashes such as
MD5, SHA1 and other algorithms.
Distributed session caching tools and APIs, primarily for SSL/TLS servers
though perhaps useful for other (non-SSL/TLS) circumstances. This also
includes a self-contained network abstraction library (libnal), and the
sslswamp SSL/TLS benchmark/test utility.
