Constructor Detail

AuthorityKeyIdentifier

protected AuthorityKeyIdentifier(ASN1Sequence seq)

AuthorityKeyIdentifier

public AuthorityKeyIdentifier(SubjectPublicKeyInfo spki)

Deprecated. create the extension using org.spongycastle.cert.X509ExtensionUtils

Calulates the keyidentifier using a SHA1 hash over the BIT STRING from SubjectPublicKeyInfo as defined in RFC2459. Example of making a AuthorityKeyIdentifier:

   SubjectPublicKeyInfo apki = new SubjectPublicKeyInfo((ASN1Sequence)new ASN1InputStream(
       publicKey.getEncoded()).readObject());
   AuthorityKeyIdentifier aki = new AuthorityKeyIdentifier(apki);

public AuthorityKeyIdentifier(SubjectPublicKeyInfo spki,
                              GeneralNames name,
                              java.math.BigInteger serialNumber)

Deprecated. create the extension using org.spongycastle.cert.X509ExtensionUtils

create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided as well.

AuthorityKeyIdentifier

public AuthorityKeyIdentifier(GeneralNames name,
                              java.math.BigInteger serialNumber)

create an AuthorityKeyIdentifier with the GeneralNames tag and the serial number provided.

AuthorityKeyIdentifier

public AuthorityKeyIdentifier(byte[] keyIdentifier)

create an AuthorityKeyIdentifier with a precomputed key identifier

AuthorityKeyIdentifier

public AuthorityKeyIdentifier(byte[] keyIdentifier,
                              GeneralNames name,
                              java.math.BigInteger serialNumber)

create an AuthorityKeyIdentifier with a precomputed key identifier and the GeneralNames tag and the serial number provided as well.
