Capabilities

Tools 2

compile_asn1_schema

Compiles ASN.1 schema definitions into executable source code. Use this tool whenever a user asks to generate code, compile an ASN.1 schema, or create a codec (e.g., DER, PER, UPER, BER) for a specific programming language. The tool returns the compilation status, error messages, and files containing the generated source code.

Discovered 21 hr ago

validate_asn1_schema

Validates ASN.1 schema definitions syntax and semantics. Use this tool whenever a user asks to validate, check, or verify an ASN.1 schema without generating source code. The tool returns a list of messages (informational, warnings, and errors).
