ASN.1's built-in simple types are shown in the following Table. The universal class number (tag) and a typical use of each type are also included. Table:Simple types in ASN.1, their universal tags, and uses. * indicates more than one tag. For a full list of Universal Tags, see th...
ASN.1 is flexible, allowing simple easily understood descriptions, yet has the power, for those who need it, to enforce complex constraints in which the type of information in one component of a message could be determined by the value of another component in the message. So ASN.1 is ...
Learn the basics of ASN.1: See a simple example, learn about the ASN.1 types, and see a description of the encoding rules. Then, you can complete your ASN.1 learning experience by taking a look at the Advanced Topics section.

Do you have a sample application that illustrates step-by-step the use of the OSS ASN.1 Compiler to compile a simple ASN.1 module, and the use of the OSS API to invoke the encoder/decoder? The following sample application illustrates the use of the OSS ASN.1 Compiler to compile a sim...
The ASN.1 UTF8String type is used for handling Unicode characters. UniversalString and UTF8String both support the same character set, however, their encoding is different.ExampleString ::= UTF8String capLetters String ::= "ABCDLMYZ" Try it on the Playground | Try it with ASN.1/Python ...
