Crate dkg_recovery 

Distributed Key Generation - Recovery

A utility function to recover a key from its secret shares.

Keys likely SHOULD NOT ever be recovered, making this primarily intended for testing purposes. Instead, the shares of the key should be used to produce shares for the desired action, allowing using the key while never reconstructing it.

Before being smashed, this crate was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc1dafb82a09d9419ea182667115df06. Any subsequent changes have not undergone auditing.
