iOS app by Shadowfetch · App Store ID 6793302636 · iOS

Derweave: ASN.1 Explorer is a focused, fully on-device app. A private ASN.1 BER/DER explorer for tag-length-value trees, OIDs, X.509 certificates, CSRs, PKCS structures, extension bytes, hex ranges, and schema-assisted decoding.

Key Features

• Decode definite BER and canonical DER TLV trees
• Map common OIDs and X.509 fields
• Inspect certificates, CSRs, and PKCS containers
• Link every node to exact source-byte ranges
• Export annotated hex and structural JSON
• Complete bundled sample and local comparison workflow
• Local PDF report and Apple system share export
• Original offline technical reference library

One-Time And Private

• One paid download; no subscription or in-app purchase
• No account, advertising, analytics, tracking, or developer-operated backend
• Core features and bundled content work offline
• Work remains on device unless you deliberately share or export it through an Apple system interface

Inspection and learning aid. Trust, revocation, policy, identity, and cryptographic validity require an appropriate validation environment.
