SES Super-Encypherment Scrambler
SES brings back the uncrackable onetime pad, with a digital twist.
SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to efficiently cipher text of arbitrary length or files of any size or type. Use it with confidence. To achieve complete one-on-one privacy, SES traverses several levels en route to its output. The more words in your key-phrase, the more layers of encipherment SES applies. It is part Vigenere, part onetime pad, part cryptographic hash, not to mention the essential scrambler element, each component driven by ISAAC, with all key-derivation and stretching relying on Keccak in 512-bit configuration. -

SSL Diagnos
SSL Strength Evaluation and Test Utility
SSL Diagnos is used to test SSL strength; get information about SSL protocols (pct, ssl2, ssl3, tls, dtls) and cipher suites. It can also be used for testing and rating ciphers on SSL clients. It has also specific support for pop3s, sip, smtp and explicit ftps. Tests for heartbleed (including dtls). Furthermore a separate tool, SSLPressure, not using openssl can be used to check the whole spectrum of possible SSL protocols on a server. Can also be used for testing ssl for mssql-servers (was added since nessus did not support this) and contains mitm poc for stripping ssl from mssql-connections. -

Wordpie Python Based Brute Force
Python Based Brute Force Password Cracking Assistant By Clownsec
A python script used to generate all possible password combinations for cracking WAP and other logins or password files. This program is open source. If you see the need to repair or change something by all means do so, but share your findings. *HONK* Usage: wordpie.py [-h] [-o OUTPUT] [-min MIN_SIZE] [-max MAX_SIZE] [-N] [-L] [-U] [-S] [-A] [-v] Generate a wordlist with all possible combinations of letters including: -L (Lowercase Letters) -U (Uppercase Letters) -N (Numbers) -S (Special Characters) -A (All Characters, Numbers, and Letters) -min (Minimum Size) -max (Maximum Size) -o outputfile.gz or -o stdout By default -o filename.gz to create a GZ compressed text file of all the words. Use the keyword "stdout" to print to screen or for use with other programs like Aircrack-ng or Medusa ./wordpie.py | xargs -L 1 medusa -h 192.168.1.1 -u admin -M web-form -p ./wordpie.py -o stdout -A | aircrack-ng -b XX:XX:XX:XX:XX:XX -w - *.cap -

Cyberbit
Visual Cryptography and Bit-Plane Complexity Segmentation in Python
Hide secret messages in your pictures! Cyberbit lets you transmit a secret message to an intended person in a new manner. The secret message is an 1-bit deep black & white image. The message can contain written text, a drawing, a secret code etc. Using Visual Cryptography the application splits the secret message into two "shadow images" called <<shares>>. Any of the two shares will be embedded into a "normal" image file called by tradition <<vessel>>. You can use a method of hand to send the two vessels to your correspondent. For instance you can post one vessel image on facebook. The other vessel image can be sent as an attachment of an e-mail. The vessel images can be 8-bit gray-level images or 24-bit deep true-color images. Anyone who can correctly spot the two vessels and knows the dimensions of the image containing the secret message will be able to decrypt the secret message using the Cyberbit application. -

Stegcore
A cross-platform crypto-steganography toolkit
Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants.
