S/Key Generator. An RFC2289 compliant One-Time Password generator written in Java language and O.S. Thinlet package for GUI.
It uses MD4 and MD5 hash algorithms.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
A graphical tool for generating RSA and ECDSA cryptographic key-pairs, creating Certificate Signing Requests (CSRs) from them, and combining the key-pair with an issued digital certificate to create a secure portable container (PKCS12, JKS, JCEKS, etc.).
With Tiger Envelopes you can stop snoops from reading your email. Same email client. No extra steps. One click to install on Windows and Linux. Configures Outlook, Thunderbird, and KMail. Supports GPG, PGP, Bouncy Castle encryption.
Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.
The main philosophy of the project is "the best protection a bad password can give". People will choose bad password as long as they have this option, so Neocryptex builds a strong crypographical defence between the password and encrypted data.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.
You asked, we delivered! Auth0 is excited to expand our Free and Paid plans to include more options so you can focus on building, deploying, and scaling applications without having to worry about your security. Auth0 now, thank yourself later.
BarTex is a system designed to create inexpensive tickets for events. It uses a crypto system to verify tickets using barcodes; thus eliminating the cost of expensive, colorful tickets that cannot be photocopied/forged.
a small library for cryptography (e.g. for the MicroEdition of Java) that supports AES (256 bit only), SHA-512 and CBC. The library is available in Java and JavaScript.
stores a free text field strongly encrypted on a cell-phone or PDA using AES encryption with 256 bit -- can be used for storing passwords, pins and other sensitive data
Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.
phpCA is a PHP-based framework to operate a certificate authority (CA). It uses the openssl functions of PHP to generate CSRs and X.509-certificates as well as mySQL to store these data.
The OpenSSL shell/batch script collection offers insight in how to setup a hierarchical PKI structure consisting of a Root CA, several sub CA's and end entity digital certificates. The scripts are available for unix and windows.
Hash Cracker is an application developed in java swings that allows a user to crack MD2, MD5, SHA-1,SHA-256,SHA-384,SHA-512 hashes either using brute force or using wordlists of the user's choice based on the users choice.
JSerpent is an easy to use Java implementation of the powerful Serpent cryptography algorithm. It can be easily implemented into any project, and is complete with ECB, padding, and a simple API.
JFish is a simple Java implementation of the popular Twofish cryptography algorithm. It allows any application to easily implement powerful encryption, using a single small library and minimal code changes.
JRijndael is a 100% pure Java implementation of the popular Rijndael (aka AES) cryptography algorithm. It's designed to be implemented as easily as possible and features ECB, padding, and a simple API.
HashserGUI is a GUI interface for Jacksum. It is intended to provide a graphical tool to create hashes for files within a directory, and check the hashes generated. It works with many hash functions, as md5, sha1, sha256, sha512, md4, crc, etc.
Bash shell scripts to run an OpenSSL Certificate Authority (CA) and issue self-signed HTTPS server certificates (or cert signing requests) for intranets. Scripts: genrootca, genservercert, genusercert, revokecert, csv2usercerts, certificate-mailer.
