Gordian Seed Tool v1.6.0 Released
Gordian Seed Tool is a cryptographic seed manager for iOS and macOS devices.
- "Gordian Seed Tool, the @BlockchainComns iOS exemplar for protecting and using your cryptographic seeds, has been updated to version 1.6," announced Christopher Allen.
- "Gordian Seed Tool is a seed vault: a place to store your cryptographic secrets. But it can also be used to sign PSBTs or to output keys to wallets," he explained.
"Fundamentally, Gordian Seed Tool is meant as an exemplar of best practices: how to store seeds securely; how to back them them up; how to use them securely. It's also an exemplar for @BlockchainComns developer specifications such as Envelope and SSKR."
- "Gordian Seed Tool 1.6 demonstrates how Envelope can be used to export seeds with metadata including notes, dates, and even descriptors. This can be crucial for recovering funds from a specific derivation path. It also shows how data elision works in Envelope. If there's too much content for a specific storage medium, metadata is elided (and can hopefully be recovered from a different share or backup)."
- "The newest version of Gordian Seed Tool also makes improvements to hex, BIP39, and Bytewords entry. These are equally crucial methods for recovering data, and we want to encourage strong ease-of-use for the entry methods. Now it also shows lifehashes of master fingerprints, as another guidance for users recognizing seeds."
- "Gordian Seed Tool 1.6 has more than half-a-year's advances in specifications, best practices, and other expansions. If you have an iOS device, take a look. To support this sort of continued work, to empower users and wallet manufacturers alike, please become a @BlockchainComns sponsor."
- Gordian Seed Tool is available from the Apple Appstore for the iPhone, or can be compiled from source here.
What's new
UI Best Practices
- BIP39/ByteWords Entry: Shows validity of individual words
- Hex Entry: More accessible entry cuts out spaces, other non-hex entries
- Seed Printing: Elides some info if necessary to print out a backup of a seed
- Fingerprint Info: Seed views now display master fingerprint & Lifehash
Resilience Best Practices
Other Chain Expansions
- Tezos Support: Generates tz1 addresses & private keys
- Ethereum & Tezos Improvements: Better shows necessary data for chains
Specification Updates
- Envelope is now prime output type for seeds, SSKR, requests, responses
- Envelope attachments are supported
- Update to Envelope v2, based on IETF feedback
- Update to Account Descriptor v2, Output Descriptor v3, based on community feedback
- Update to IANA registered CBOR numbers (with backward compatibility as needed)
- General bug fixes and improvements.
