getDigest

public OCTET_STRING getDigest()

getTag

public Tag getTag()

Description copied from interface: ASN1Value

Returns the base tag for this type, not counting any tags that may be imposed on it by its context.

Specified by:

getTag in interface ASN1Value

Returns:

Base tag.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

byteArraysAreSame

private static boolean byteArraysAreSame(byte[] left,
 byte[] right)

Compares two non-null byte arrays. Returns true if they are identical, false otherwise.

encode

public void encode(OutputStream ostream)
            throws IOException

Description copied from interface: ASN1Value

Write this value's DER encoding to an output stream using its own base tag.

Specified by:

encode in interface ASN1Value

Parameters:

ostream - Output stream.

Throws:

IOException - If an error occurred.

encode

public void encode(Tag implicitTag,
 OutputStream ostream)
            throws IOException

Description copied from interface: ASN1Value

Write this value's DER encoding to an output stream using an implicit tag.

Specified by:

encode in interface ASN1Value

Parameters:

implicitTag - Implicit tag.

ostream - Output stream.

Throws:

IOException - If an error occurred.
