2022-03-28[age restriction] progress 19/19 (final) - Use Edx25519 for cryptoÖzgür Kesim
We switch from EcDSA to Edx25519 for the underlying signature scheme. Edx25519 is implemented in gnunet, starting with (gnunet-)commit ce38d1f6c9bd7857a1c3bc2094a0ee9752b86c32.

2022-03-03[age restriction] progress 18/n - attestation testedÖzgür Kesim
- Unit-tests for commit, derive, attest and verify added, with multiple combinations of minimum age and commited age. - Fixed crypto implementation (eddsa -> ecdsa) - Using now standard functionality from GNUNET: GNUNET_CRYPTO_ecdsa_{private,public}_key_derive All tests pass (unit tests in util/ and 'make check' in testing).

- functions TALER_age_commitment_attest and TALER_age_commitment_verify implemented. - age restriction implementation moved into util/age_restriction.c
2022-03-01[age restriction] progress 17/n - attestation implementedÖzgür Kesim
- functions TALER_age_commitment_attest and TALER_age_commitment_verify implemented. - age restriction implementation moved into util/age_restriction.c
2022-03-01Refactoring TALER_AgeCommitmentÖzgür Kesim
Instead of a single struct TALER_AgeCommitment, we now use 1. TALER_AgeCommitment for the age mask and list public keys for age restriciton. 2. TALER_AgeProof for list of private keys for age restriction 3. TALER_AgeCommitmentProof for the aggregation of the former two. Also, we introduce TALER_AgeAttestation as the EDDSA signature to attest a particular age group, along with the function prototypes TALER_age_commitment_attest and TALER_age_commitment_verify.
2022-02-28-towards getting auditor tests to pass again with new logicChristian Grothoff
2022-02-22[age restriction] progress 16/n - refresh/reveal/link testsÖzgür Kesim
Age restriction works now with withdraw, melt/refresh/reveal and link, including tests. However, there is still a problem with the tests: The melting operation "refresh-melt-failing-age" that should fail (because of conflict), but currently fails for other reasons. I decided to disable that particular test (and the next) and submit the patch I have so far.
