KeyUsage介绍

[英]The KeyUsage object.

id-ce-keyUsage OBJECT IDENTIFIER ::=  { id-ce 15 } 
KeyUsage ::= BIT STRING { 
digitalSignature        (0), 
nonRepudiation          (1), 
keyEncipherment         (2), 
dataEncipherment        (3), 
keyAgreement            (4), 
keyCertSign             (5), 
cRLSign                 (6), 
encipherOnly            (7), 
decipherOnly            (8) }
