XYGATE /ESDK

Certificate

Module description

The XYGATE Encryption Software Development Kit [XESDK] is a dynamically linked software library that supplies: symmetric key encryption including the approved AES and TripleDES; hashing algorithms including the approved SHA-1 and SHA-256; public key encryption including RSA; signature algorithms including the approved RSA and DSA; secure session protocols such as SSH, SSL and TLS and e-mail protocols such as PGP and S/MIME. Based on cryptlib by Peter Gutmann, the XESDK, written in C, provides encryption services for applications, communications and databases across multiple computer platforms.

Approved algorithms

Other algorithms

Blowfish; CAST-128; DES; Diffie-Hellman (key agreement; key establishment methodology provides between 112 and 152 bits of encryption strength; non-compliant less than 112 bits of encryption strength); ElGamal; HMAC MD5; HMAC RIPE-MD; IDEA; MD2; MD4; MD5; RC2; RC4; RC5; RIPE-MD; RSA (key wrapping; key establishment methodology provides between 112 and 152 bits of encryption strength; non-compliant less than 112 bits of encryption strength); Skipjack (non-compliant)
