包路径：java.security.cert.X509Certificate
类名称：X509Certificate
方法名：getKeyUsage

X509Certificate.getKeyUsage介绍

[英]Returns the KeyUsage extension as a boolean array.

The ASN.1 definition of KeyUsage:

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

[中]以布尔数组的形式返回KeyUsage扩展名。
ASN。1键用法的定义：

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