S-DES Crypto App
Encryption/Decryption demonstration app using the S-DES algorithm
Encryption/Decryption demonstration app using the S-DES algorithm. Use the Java runtime environment 11 for execution. The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes. -

SimpleKey
Generates keys up to 500 characters and hashes.
Ever wanted a random key generator? With SimpleKey, you can generate random keys up to 500 characters in length and save them to text files. These keys can be all numerical, alphanumeric, all alphabetical or the previous three plus special characters. You may use your generated key for whatever purpose. SimpleKey also includes a hash table with which to hash strings and files alike. Hash algorithms include: MD4/5, Sha, Skein, Keccak, Grostl, JH, and Blake. -

StrongKey PKI2FIDO
Web application to register FIDO keys from TLS ClientAuth sessions
StrongKey PKI2FIDO is a web application written in Angular and Java using REST web service calls for client-server communication. The application enables users that have X.509 digital certificates (optionally, on smart cards—such as the PIV card or CAC) to strongly authenticate to PKI2FIDO using TLS ClientAuth and then register a FIDO Security key with a FIDO Server (such as StrongKey FIDO Server at https://sourceforge.net/projects/strongkeyfido/). The TLS ClientAuth strong authentication process validates the digital certificate's chain (if any) and uses CRLs to verify the certificate's revocation status (OCSP checking will come in the next release). Once the certificate chain is validated, it checks an LDAP server to determine if the user is authorized to register a FIDO Security key with the site. Since PKI2FIDO is a sample application, a De-register button is enabled to delete FIDO keys; This enables the user to keep testing with the same username. -
