We have an implementation gaining Squeak/Pharo/Gemstone/Swift, as well as an implementation in Java. Needs for ASN1, including ASN1Choice, ASN1Real, ASN1Explicit, as well as Cryptographic entities as SHA1HMAC, MD5, RSA Keys, Ciphers by name. With these features, ports can be made.
We would like to see new ports of implementation to new language environments.
