Examples of sun.security.util.DerValue

sun.security.util.DerValue
Represents a single DER-encoded value. DER encoding rules are a subset of the "Basic" Encoding Rules (BER), but they only support a single way ("Definite" encoding) to encode any given value.
All DER-encoded data are triples {type, length, data}. This class represents such tagged values as they have been read (or constructed), and provides structured access to the encoded data.
At this time, this class supports only a subset of the types of DER data encodings which are defined. That subset is sufficient for parsing most X.509 certificates, and working with selected additional formats (such as PKCS #10 certificate requests, and some kinds of PKCS #7 data). A note with respect to T61/Teletex strings: From RFC 1617, section 4.1.3 and RFC 3280, section 4.1.2.4., we assume that this kind of string will contain ISO-8859-1 characters only. @author David Brownell @author Amit Kapoor @author Hemma Prafullchandra
