Constructors Summary
public X509KeyUsage(int usage)
Basic constructor.
param
usage - the bitwise OR of the Key Usage flags giving the allowed uses for the key. e.g. (X509KeyUsage.keyEncipherment | X509KeyUsage.dataEncipherment)
this.usage = usage;
Methods Summary
public org.bouncycastle.asn1.DERObject toASN1Object()
return new KeyUsage(usage);
