ASN.1 Compilation Services

Convert your ASN.1 specifications into TypeScript, JavaScript, JSON Schema, BSON Schema, and more.

ASN.1 is just as hard for a computer to understand as it is for humans. It could take years and millions of dollars in development for a competent team to implement a fully-featured ASN.1-based protocol. With Wildboar Software's ASN.1 Compilation Services, we can turn your specifications into hundreds of thousands of lines of correct code for pennies on the dollar.

Example

The compiled output below is not exactly what compilation would produce. This is only an example.

ASN.1 Before Compilation

TBSCertificate ::= SEQUENCE { version [0] Version DEFAULT v1, serialNumber CertificateSerialNumber, signature AlgorithmIdentifier{{SupportedAlgorithms}}, issuer Name, validity Validity, subject Name, subjectPublicKeyInfo SubjectPublicKeyInfo, issuerUniqueIdentifier [1] IMPLICIT UniqueIdentifier OPTIONAL, ..., [[2: -- if present, version shall be v2 or v3 subjectUniqueIdentifier [2] IMPLICIT UniqueIdentifier OPTIONAL]], [[3: -- if present, version shall be v2 or v3 extensions [3] Extensions OPTIONAL ]] -- If present, version shall be v3]] } (CONSTRAINED BY { -- shall be DER encoded -- } ) Certificate ::= SIGNED{TBSCertificate}

Resulting TypeScript from Compilation

class TBSCertificate { constructor ( readonly version: OPTIONAL<Version>, readonly serialNumber: CertificateSerialNumber, readonly signature: AlgorithmIdentifier, readonly issuer: Name, readonly validity: Validity, readonly subject: Name, readonly subjectPublicKeyInfo: SubjectPublicKeyInfo, readonly issuerUniqueIdentifier: OPTIONAL<UniqueIdentifier>, readonly _unrecognizedExtensionsList: _Element[] = [], ) {} } type Certificate = SIGNED<TBSCertificate>; function _decode_Certificate ( el: _Element, ) { // ... } function _encode_Certificate ( value: Certificate, elGetter: $.ASN1Encoder<Certificate>, ) { // ... }
