Method Detail

encode

public static byte[] encode(org.bouncycastle.asn1.ASN1Encodable value)

resourceToBitString

public static org.bouncycastle.asn1.DERBitString resourceToBitString(net.ripe.ipresource.UniqueIpResource resource,
                                                                     int bitCount)

decode

public static org.bouncycastle.asn1.ASN1Primitive decode(byte[] extension)

Decodes the byte array extension using the ASN1InputStream.

expect

public static <T extends org.bouncycastle.asn1.ASN1Encodable> T expect(org.bouncycastle.asn1.ASN1Encodable value,
                                                                       Class<? extends T> expectedClass)

Checks if value is an instance of the expectedClass.

Throws:

IllegalArgumentException - the instance is null or not an instance of the expected class.

parseIpAddressAsPrefix

public static net.ripe.ipresource.IpRange parseIpAddressAsPrefix(net.ripe.ipresource.IpResourceType type,
                                                                 org.bouncycastle.asn1.ASN1Encodable der)

IpAddress used as a prefix.

parseIpAddress

public static net.ripe.ipresource.IpAddress parseIpAddress(net.ripe.ipresource.IpResourceType type,
                                                           org.bouncycastle.asn1.ASN1Encodable der,
                                                           boolean padWithOnes)

IPAddress ::= BIT STRING

parseAsId

public static net.ripe.ipresource.Asn parseAsId(org.bouncycastle.asn1.ASN1Encodable der)

ASId ::= INTEGER

Throws:

IllegalArgumentException - when the wrong encoding is used or value is not a valid 32-bit ASN.

encodeIpAddress

public static org.bouncycastle.asn1.DERBitString encodeIpAddress(net.ripe.ipresource.IpRange prefix)

IPAddress ::= BIT STRING
