Module description
Quoted from the NIST CMVP entry for this certificate.
The ZixCorp Crypto Module provides email encryption using a FIPS 140-2 level 1 validated cryptographic module. As part of the Zix Email Encryption Service, the ZixCorp Crypto Module provides highly secure email communication between Zix customers and their business partners. The approved cryptographic algorithms included in the module are: AES, Triple- DES, RSA, SHA-1, HMAC SHA-1 and FIPS 186-2 Appendix 3.1 RNG.
Approved algorithms (6)
Other algorithms
DSA (non compliant); Diffie-Hellman (key agreement); Elliptic Curve (non compliant); MD2; MD5; HMAC MD5; RSA (key wrapping; key establishment methodology provides 112-bits of encryption strength; non-compliant less than 112 bits of encryption strength)
Tested configurations
- Microsoft Linux Red Hat Enterprise 3 Operating System (in single user mode)
