Public key cryptography
CryptoSys PKI Pro is a library to carry out public key cryptography using RSA and ECDSA. You can generate and manage X.509 certificates, PKCS#8/PKCS#12 private keys and CMS/PKCS#7 objects. Includes all required supporting cryptographic utilities.
Symmetric cryptography
CryptoSys API provides "symmetrical" encryption using block ciphers like AES and Triple DES; stream ciphers ArcFour, Salsa and ChaCha20; message authentication algorithms HMAC, CMAC and KMAC; hash functions SHA-1, SHA-2 and SHA-3; and more.
XML canonicalization
SC14N performs the canonicalization (C14N) transformation you need to do when creating signed XML documents using XML-DSIG. It can carry out both "inclusive" and "exclusive" canonicalization. Includes a command-line interface.
XML simple query
xmlsq is a free simple lightweight utility to query XML documents using XPath 1.0. Use from the command line or via its programming interface.
QR code generator
diQRcode enables you to generate QR code images directly from your code or the command line.
