A Native ASN.1 Workbench for macOS
July 21, 2026
Inyo Systems introduced ASN1, a native macOS workspace that keeps schemas, JSON values, encoded payloads, and diagnostics together. It supports writing and validating ASN.1 schemas; encoding and decoding BER, DER, OER, PER, UPER, and XER; GSER encoding; and visual inspection of BER and DER structures. Processing takes place locally on the Mac.
