From 8bdf6ab19df70c16d335ecf82f2c3b2117eeb70e Mon Sep 17 00:00:00 2001 From: Özgür Kesim Date: Wed, 16 Feb 2022 22:01:05 +0100 Subject: [age restriction] progress 14/n - withdraw and deposit Age restriction support for - withdraw is done and tested - deposit is done and tested TODOs: - melt/refresh/reveal - link ------ Added functions - TALER_age_restriction_commit - 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 - Fixes of post handler for /management/extensions - Fixes for offline tool extensions signing - Slight refactoring of extensions - Age restriction extension simplified - config is now global to extension - added global TEH_age_restriction_enabled and TEH_age_mask in taler-exchange-httpd - helper functions and macros introduced --- src/exchangedb/test_exchangedb.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) (limited to 'src/exchangedb/test_exchangedb.c') diff --git a/src/exchangedb/test_exchangedb.c b/src/exchangedb/test_exchangedb.c index 0622e069..f9e64fdc 100644 --- a/src/exchangedb/test_exchangedb.c +++ b/src/exchangedb/test_exchangedb.c @@ -458,6 +458,7 @@ static unsigned int auditor_row_cnt; * @param cls closure * @param rowid unique serial ID for the refresh session in our DB * @param denom_pub denomination of the @a coin_pub + * @param h_age_commitment hash of age commitment that went into the minting, may be NULL * @param coin_pub public key of the coin * @param coin_sig signature from the coin * @param amount_with_fee amount that was deposited including fee @@ -470,6 +471,8 @@ static enum GNUNET_GenericReturnValue audit_refresh_session_cb (void *cls, uint64_t rowid, const struct TALER_DenominationPublicKey *denom_pub, + const struct + TALER_AgeCommitmentHash *h_age_commitment, const struct TALER_CoinSpendPublicKeyP *coin_pub, const struct TALER_CoinSpendSignatureP *coin_sig, const struct TALER_Amount *amount_with_fee, @@ -1475,8 +1478,8 @@ run (void *cls) { struct TALER_PlanchetDetail pd; struct TALER_CoinSpendPublicKeyP coin_pub; - struct TALER_AgeHash age_hash; - struct TALER_AgeHash *p_ah[2] = { + struct TALER_AgeCommitmentHash age_hash; + struct TALER_AgeCommitmentHash *p_ah[2] = { NULL, &age_hash }; @@ -1597,7 +1600,7 @@ run (void *cls) deadline = GNUNET_TIME_timestamp_get (); { struct TALER_DenominationHash dph; - struct TALER_AgeHash agh; + struct TALER_AgeCommitmentHash agh; FAILIF (TALER_EXCHANGEDB_CKS_ADDED != plugin->ensure_coin_known (plugin->cls, @@ -1847,7 +1850,7 @@ run (void *cls) uint64_t new_known_coin_id; struct TALER_CoinPublicInfo new_coin; struct TALER_DenominationHash dph; - struct TALER_AgeHash agh; + struct TALER_AgeCommitmentHash agh; bool recoup_ok; bool internal_failure; @@ -2201,7 +2204,7 @@ run (void *cls) { uint64_t known_coin_id; struct TALER_DenominationHash dph; - struct TALER_AgeHash agh; + struct TALER_AgeCommitmentHash agh; FAILIF (TALER_EXCHANGEDB_CKS_ADDED != plugin->ensure_coin_known (plugin->cls, -- cgit v1.2.3
