zkCompte ya email na Noir & Aztec - Eteni ya 1

Merci munene na équipe ya Mach34 pona version initiale ya zkemail na Noir .

Maloba ya ebandeli

Compte zkEmail ezali compte ya contrat ya mayele oyo epesaka nzela na basaleli mpo na kondimisa ba transactions na koyanola na email. Ndenge nini esalaka? Message email moko na moko e signer na fournisseur ya email ya mosaleli (ndakisa, iCloud, Gmail to ProtonMail). Compte ya contrat intelligent ya mosaleli e vérifier signature en chaîne mpe e exécuter transaction soki signature ezali valide. En plus ya vérification ya signature, ezali pe important ya ko vérifier yango

1. email etindamaki uta na adresse email ya mosaleli, .
2. etindamaki na adresse email ya relayer mpe
3. que email ezali na sujet correct(oyo ezali na calldata to description ya tx).

Ndakisa

Alice atindi email oyo elandi na relayer moko:

 from: [email protected] to: [email protected] subject: Send 10 ETH to vitalik.eth DKIM-Signature: /* signature by icloud.com */ /* body is not relevant */

Bomoni motó ya likambo DKIM-Signature ? Ezali signature oyo esalemi na clé privée ya iCloud. Lisolo oyo etikali ekolimbola boye:

1. Nini mpenza etiamaki sinyatili na mopesi ya email
2. Ndenge nini kozua clé publique ya fournisseur ya email
3. Ndenge nini ko vérifier signature na Noir

Siniatire

Signature ya DKIM esalemi na fournisseur ya email oyo a signer sous-ensemble ya ba têtes na ordre correct mpe format canonique. Totala motó ya likambo moko ya DKIM-Signature:

Ezali na ba paires ya valeur-clé oyo ekabwani na ba demi-colons. Biteni ya ntina ezali: a= mpe b= . Tobuka yango na nse:

• a= ezali algorithme oyo esalelamaka pona ko signer message. Na likambo oyo, ezali rsa-sha256 .
• b= ezali signature yango moko na encodage ya base64.

Nini ezali mpenza na sinyatili?

Ba têtes ya email e classer pe e canonicalisé avant ya ko signer. Molongo ya mitó elakisami na paramètre h= ya motó ya DKIM-Signature . Na nsima mitó ebongolami na makomi mike, esika ya mpɛmbɛ mosusu elongolami, mpe na nsima esangisami na bilembo \r\n . Tika totala ba têtes avant canonicalisation:

Fungola ya bato nyonso ya mopesi ya email

Mituna 2:

1. Ndenge nini kozwa clé publique ya fournisseur ya email?
2. Ndenge nini ko vérifier signature na Noir?

Soki otali motó ya DKIM-Signature uta likolo, okomona 2 paramètres: d=icloud.com mpe s=1a1hai . Yango ezali d omain mpe s elector ya fournisseur ya email. Tokoki kozwa fungola ya bato banso na kotuna enregistrement ya DNS ya sikisiki: {s}._domainkey.{d} . Na likambo oyo, esengeli totuna 1a1hai._domainkey.icloud.com . Tosala query na yango na nzela ya commande dig :

Tozwi eyano oyo elandi:

Eteni ya kosepelisa ezali paramètre p= . Toyebi ete ekabolami na milɔngɔ ya ba citations ebele, yango wana tosengeli kosangisa yango esika moko. Litomba na yango ezali boye:

Oyo ezali clé publique ya fournisseur ya email( iCloud.com ) encodé na base64. Tokosalela yango sima pona ko vérifier signature na Noir.

Circuit ya Noir

Na tina ya ba limitations ya ba circuits ZK, esengeli tosalela mise en œuvre spécifiquement optimisée ya RSA na ba nombres minene oyo epesami na équipe ya Noir: https://github.com/noir-lang/noir_rsa .

Botia yango na Nargo.toml:

 [dependencies] noir_rsa = { tag = "v0.2", git = "https://github.com/noir-lang/noir_rsa" }

Sikoyo, totala circuit ya Noir pona vérification:

 use noir_rsa::bignum::BigNum; use noir_rsa::bignum::runtime_bignum::BigNumInstance; use noir_rsa::bignum::fields::Params2048; use noir_rsa::RSA; global PUBKEY_LIMBS_LEN: u32 = 18; global SIGNATURE_LIMBS_LEN: u32 = 18; type BN2048 = BigNum<18, Params2048>; type RSA2048 = RSA<BN2048, BigNumInstance<18, Params2048>, 256>; global rsa: RSA2048 = RSA {}; fn verify_email<let MAX_HEADERS_LEN: u32>( headers: [u8; MAX_HEADERS_LEN], headers_len: u32, pubkey_limbs: [Field; PUBKEY_LIMBS_LEN], pubkey_redc_limbs: [Field; PUBKEY_LIMBS_LEN], signature: [Field; SIGNATURE_LIMBS_LEN] ) -> bool { let signature: BN2048 = BigNum::from_array(signature); let pubkey: BigNumInstance<18, Params2048> = BigNumInstance::new(pubkey_limbs, pubkey_redc_limbs); let headers_hash = std::hash::sha256_var(headers, headers_len as u64); rsa.verify_sha256_pkcs1v15(pubkey, headers_hash, signature) }

Nako sauter ba importations na ba définitions ya type pona brevité(nani amibanzabanzaka de toute façon, kaka copier-coller yango). Totala ba paramètres verify_email :

• headers : ba têtes canonicalisées lokola ensemble ya ba octets. Ezali na bolai oyo ebongwani mpe esengeli kozala na 0 na nsuka
• headers_len : bolai ya solo ya mitó
• pubkey_limbs & pubkey_redc_limbs : fungola ya bato banso ya mopesi ya email oyo e coder mpenza mpo na Noir
• signature : signature ya fournisseur ya email oyo e coder spécifiquement pona Noir

Na nzoto ya fonction, tobongoli liboso signature na clé publique na ba instances ya nombre munene. Na sima to hash ba têtes canonicalisées na sha256 pe to vérifier signature na clé publique na hash.

 let signature: BN2048 = BigNum::from_array(signature); let pubkey: BigNumInstance<18, Params2048> = BigNumInstance::new(pubkey_limbs, pubkey_redc_limbs); let headers_hash = std::hash::sha256_var(headers, headers_len as u64); rsa.verify_sha256_pkcs1v15(pubkey, headers_hash, signature)

Soki botalisi elongi, mosala ekozongisa true , soki te ekozongisa false .

Kobanda na molongo ya email brut tii na ba entrées ya Noir

Sikoyo, lokola tozali na circuit Noir, ndenge nini to convertir chaîne email brute na ba entrées structurées pona circuit?

Tobanda na ba têtes. Nakosalela mailparser pona ko parser email na dkim pona kobimisa ba têtes canonicalisées. Parse ya email yango:

 import DKIM from "dkim"; import { simpleParser } from "mailparser"; async function canonicalizeHeaders(emailStr: string) { const email = await simpleParser(emailStr); const dkimHeader = email.headers.get("dkim-signature").params; const canonicalHeaders = DKIM.processHeader( email.headerLines.map((x) => x.line), dkimHeader.h.split(":").map((x) => x.trim()), "relaxed", ); const signatureBase64 = dkimHeader.b.replace(/\s/g, ""); return { canonicalHeaders, signatureBase64 }; }

Sikoyo, meká yango:

 const { canonicalHeaders, signatureBase64 } = await canonicalizeHeaders( String.raw` DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=icloud.com; s=1a1hai; t=1693038337; bh=7xQMDuoVVU4m0W0WRVSrVXMeGSIASsnucK9dJsrc+vU=; h=from:Content-Type:Mime-Version:Subject:Message-Id:Date:to; b=EhLyVPpKD7d2/+h1nrnu+iEEBDfh6UWiAf9Y5UK+aPNLt3fAyEKw6Ic46v32NOcZD M/zhXWucN0FXNiS0pz/QVIEy8Bcdy7eBZA0QA1fp8x5x5SugDELSRobQNbkOjBg7Mx VXy7h4pKZMm/hKyhvMZXK4AX9fSoXZt4VGlAFymFNavfdAeKgg/SHXLds4lOPJV1wR 2E21g853iz5m/INq3uK6SQKzTnz/wDkdyiq90gC0tHQe8HpDRhPIqgL5KSEpuvUYmJ wjEOwwHqP6L3JfEeROOt6wyuB1ah7wgRvoABOJ81+qLYRn3bxF+y1BC+PwFd5yFWH5 Ry43lwp1/3+sA== from: [email protected] Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Mac OS X Mail 16.0 \(3731.500.231\)) Subject: Hello Message-Id: <[email protected]> Date: Sat, 26 Aug 2023 12:25:22 +0400 to: [email protected] `.trim(), ); console.log("signature:", signatureBase64); console.log(); console.log("headers:", JSON.stringify(canonicalHeaders));

Sikoyo, tobongola clé publique ya fournisseur ya email mpe signature na Noir big number limbs. Ezali kaka na bibliothèque officielle oyo ya Rust oyo ezali. Mais oza na chance po na compilé yango na wasm pe na publié yango na npm. To installer yango:

 npm i @shieldswap/email_account_utils_rs

Endimi fungola ya bato banso mpe sinyatili na base64 mpe ezongisaka maboko ya fungola ya bato banso mpe maboko ya sinyatili na format JSON:
