Crate penumbra_custody

Implementations of custody services responsible for signing transactions.

This crate currently focuses on the soft_kms implementation, a basic software key management system that can perform basic policy-based authorization or blind signing.

Modules

• encrypted
• null_kms
  A basic software key management system that stores keys in memory but presents as an asynchronous signer.
• policy
  A set of basic spend authorization policies.
• soft_kms
  A basic software key management system that stores keys in memory but presents as an asynchronous signer.
• threshold

Structs

• AuthorizeRequest
  A transaction authorization request submitted to a custody service for approval.
• AuthorizeValidatorDefinitionRequest
  A validator definition authorization request submitted to a custody service for approval.
• AuthorizeValidatorVoteRequest
  A validator vote authorization request submitted to a custody service for approval.

Enums

• PreAuthorization
  A pre-authorization packet. This allows a custodian to delegate (partial) signing authority to other authorization mechanisms. Details of how a custodian manages those keys are out-of-scope for the custody protocol and are custodian-specific.

Traits

• CustodyClient
  A well-typed wrapper around the GRPC custody protocol that uses Rust domain types rather than proto types.
