Examples of org.bouncycastle2.asn1.ASN1InputStream

org.bouncycastle2.asn1.ASN1InputStream
a general purpose ASN.1 decoder - note: this class differs from the others in that it returns null after it has read the last object in the stream. If an ASN.1 NULL is encountered a DER/BER Null object is returned.
