Porting notes from the old ASN.1 library For the most part code using the old subset of ASN.1 classes should be easy to transfer, providing the following changes are made:
- DERObject becomes ASN1Object
- DEREncodable becomes ASN1Encodable
- getDERObject() becomes toASN1Object()
- BERConstructedOctetString becomes BEROctetString
- If you were using the older mutable DERConstructedSequence/Set and BERConstructedSequence, use an ASN1EncodableVector in conjunction with DERSequence/Set and BERSequence
- BERInputStream and DERInputStream are replaced with ASN1InputStream
- AsymmetricKeyParameter is now in the org.bouncycastle.crypto namespace

Prior Releases
The original C# port: lcrypto-csharp-119.zip - note: the original port is now well out of date, we strongly recommend migrating to the official release stream, apart from anything BigInteger is substantially faster and the new release supports OpenPGP, PKCS12, CMS, and TSP as well.
MD5 checksum 3d95c79f6d5c6809a44d0032f64d33e0
Patch, 22 Nov 2004: BigInteger.cs Fix to prevent BigInteger prime generation in original port from going into an infinite loop.
