Identity Management
Configuring and Implementing Authorization in OpenEdge : User ID patterns as ACLs and ABL permissions checking : IV


Initialization vector, an optional binary value that is used in conjunction with a second binary [key] value to produce a two-factor encryption key. Not all cipher specifications allow the use of an IV. (Theory: the IV and key are stored, owned, and access-controlled as separate entities so that an attacker must break into two locations to obtain the full encryption key.)
