* Partial move to ff 0.13 It turns out the newly released k256 0.12 isn't on ff 0.13, preventing further work at this time. * Update all crates to work on ff 0.13 The provided curves still need to be expanded to fit the new API. * Finish adding dalek-ff-group ff 0.13 constants * Correct FieldElement::product definition Also stops exporting macros. * Test most new parts of ff 0.13 * Additionally test ff-group-tests with BLS12-381 and the pasta curves We only tested curves from RustCrypto. Now we test a curve offered by zk-crypto, the group behind ff/group, and the pasta curves, which is by Zcash (though Zcash developers are also behind zk-crypto). * Finish Ed448 Fully specifies all constants, passes all tests in ff-group-tests, and finishes moving to ff-0.13. * Add RustCrypto/elliptic-curves to allowed git repos Needed due to k256/p256 incorrectly defining product. * Finish writing ff 0.13 tests * Add additional comments to dalek * Further comments * Update ethereum-serai to ff 0.13 |

Modular FROST
A modular implementation of FROST for any curve with a ff/group API. Additionally, custom algorithms may be specified so any signature reducible to Schnorr-like may be used with FROST.
A Schnorr algorithm is provided, of the form (R, s) where s = r + cx, which
allows specifying the challenge format. This is intended to easily allow
integrating with existing systems.
This library offers ciphersuites compatible with the IETF draft. Currently, version 11 is supported.
This library was audited by Cypher Stack in March 2023, culminating in commit 669d2dbffc1dafb82a09d9419ea182667115df06. Any subsequent changes have not undergone auditing. While this audit included FROST's definition of Ed448, the underlying Ed448 ciphersuite (offered by the ciphersuite crate) was not audited, nor was the minimal-ed448 crate implementing the curve itself.
