- TALER_age_commitment_derive
- TALER_age_commitment_hash
- TALER_age_restriction_commitment_free_inside
- Hash of age commitment passed around API boundaries
Exchangedb adjustments for denominations
- all prepared statements re: denominations now handle age_mask
- signature parameters adjusted
Hash and signature verification of /keys adjusted
- Hashes of (normal) denominations and age-restricted denominations are
calculated seperately
- The hash of the age-restricted ones will then be added to the other
hash
- The total hash is signed/verified
Tests for withdraw with age restriction added
- TALER_EXCHANGE_DenomPublickey now carries age_mask
- TALER_TESTING_cmd_withdraw_amount* takes age parameter
- TALER_TESTING_find_pk takes boolean age_restricted
- WithdrawState carries age_commitment and its hash
- withdraw_run derives new age commitment, if applicable
- Added age parameter to testing (13 as example)
Various Fixes and changes
