Petoron Quantum Standard (PQS) v1.2 A fully custom, offline encryption standard - built entirely from scratch. PQS v1.2 is a minimalistic, self-contained encryption engine for secure file protection, with zero reliance on external cryptographic libraries. PBKDF2-HMAC-SHA256 (200k iterations, adjustable) for password hardening. Key separation via BLAKE2s - independent keys for encryption and MAC. BLAKE2s-MAC authentication - 16-byte tag, any modification = instant rejection. Streaming keystream generator - secure, large-scale XOR without key reuse. Fake padding (HEAD/TAIL) - obfuscates binary boundaries and payload structure. Precise size encoding - restores original payload exactly. Supports files up to 128 MB per encrypted block. No dependencies, fully offline, cross-platform Python implementation. PQS is designed for high-assurance security, full auditability, and deterministic offline use - without unnecessary complexity. https://github.com/01alekseev/PQS

Petoron Time Burn Cipher (PTBC) A promising cipher based on self-destruction of time, complete absence of traces and impossibility of key selection. Key features: AES-CFB encryption with per-file IV Argon2id key derivation with 256MB RAM resistance TTL (time to live) built directly into the encrypted file HMAC-SHA512 integrity verification Self-deleting mode (--autowipe) and one-time access marking (--onetime) No file metadata, no recovery, no password resets Philosophy: If you lose the password - it’s over. If time expires - it’s gone. PTBC doesn’t forgive, doesn’t forget, and doesn’t leak. https://github.com/01alekseev/PTBC

This (Python) tool allows you to easily create FPGA bitfiles for your embedded system, from several Open Source IPs (compatibles with the OpenCores Wishbone bus) . It will also generates the corresponding drivers (currently only Linux ones).

Software to identify cavities and crevices in proteins. The goal is to be able to take a protein structure, and to differentiate between five different types of environments for each residue: buried, surface, interfacial, cavity, or crevice.

The C Protein Folding Library is a minimalistic, high-performance modular library of C functions and data structures for computing folding simulations of proteins on a wide variety of computer hardware.

Sign up to our mailing list at http://www.protospacer.com/contact.html. Protospacer allows researchers to build, analyze, and share their own database of CRISPR target-sites. This enables the development of custom libraries and helps to transfer the CRISPR technology to new organisms. Each Protospacer database is a simple catalogue of all possible Cas9 target-sites within a given FASTA sequence, i.e. all NGG/NAG sites. Protospacer then allows the user to sub-select targets from the database by gene ID, by exon/intron/UTR location, by sequence similarity, or by genomic co-ordinate. From here, users are able to evaluate potential off targeting, to export results in FASTA format or tabulated (e.g. for Microsoft Excel), and to connect to the Integrative Genomics Viewer (IGVref) and view target-sites in the context of genomic annotations, amino acid translations, and HT-Seq data (for off-target validation). We provide online video tutorials and a toy database from our main website.
