    htrace.sh

    htrace.sh

    My simple Swiss Army knife for http/https troubleshooting

    ...The script emphasizes operability: you can run quick checks against URLs to reveal redirects, protocol negotiation, and response timing without assembling a pile of one-off commands. It supports profiling scenarios useful during incidents, such as confirming cipher support, verifying chain validity, or flagging misconfigurations. Since it’s just a script, it runs on typical Linux servers where installing a heavy GUI isn’t feasible. The goal is to reduce the friction between “I wonder what this endpoint is doing” and a readable, actionable report.

    __Alien Cipher

    __Alien Cipher

    A bespoke symmetric cipher.

    Released under 'Creative Commons v3' license Alien Cipher is an endeavour to build my own symmetric cipher. The primary aim is to simply learn the fundamentals and finer details of cryptography in general and build working examples of my ideas in code. The code is shared here for posterity (future folk) in the guise that it may help others also on the path to cryptography. This code demo uses a 256bit rolling hash table (8x8bytes) at its heart to mix together pre-defined parameters in a way that allows the cipher to produce encoded output that is locked to a key of arbitrary length without padding. ...

    approach to encryption and decryption involves two strings. The first is an encryption / decryption string which we will allow to be up to 128 lower case alphabetical characters in length. The second string is a line of text from a file that is to be encrypted or decrypted. the basic strategy for encrypting data is based on mapping alphabetical characters to specific values, then doing some simple mathematical operations to create a new value.

    d-crypt

    Tweakable 256-bit symmetrical block cipher.

    D-crypt is an symmetrical block cipher operating on 256bit blocks with an key of the same length. The cipher takes 3 inputs: the data to encrypt, the symmetric key and a tweak consisting in a array of 16 integers representing each one of eleven possible keyaddition algorithms. Features a similar structure as AES (uses simpler versions of ShiftRows, MixColumns) and uses AES SBOX.

    NetCrypt - file-transfer utility providing secure data transfer

    ...No public key distribution is required: NetCrypt is designed to use a symmetric passphrase with a strong key-derivation-function. NetCrypt seeks to fulfill all those requirements. In it's default configuration, it uses the AES-256-GCM cipher with a PBKDF2 key iteration count of 32000 rounds. NetCrypt is an secure alternative to netcat, but might also supplement SFTP or SSH for file-transfer.

    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. ...

    ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ...

    JCryptor

    JCryptor is an encrypting tool based on the Caesar-cipher.

    JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world.
