[hide]Description
Ultibo ASN.1 interface unit
Abstract Syntax Notation One (ASN.1) is an interface description language for defining data structures that can be serialized and deserialized in a standard, cross-platform way. It's broadly used in telecommunications and computer networking, and especially in cryptography.
This unit currently only provides the basic functionality required by X509 to read and parse a certificate in DER format.
It is expected that this unit will be expanded to incorporate additional functions over time.
