zkEmail Konti muri Noir & Aztec - Igice cya 1

Ndashimira cyane ikipe ya Mach34 kuri verisiyo yambere ya zkemail muri Noir .

Intangiriro

Konti ya zkEmail ni konte yamasezerano yubwenge yemerera abakoresha kwemeza ibikorwa basubiza imeri. Bikora gute? Buri butumwa bwa imeri bwashyizweho umukono na imeri ukoresha imeri (urugero, iCloud, Gmail cyangwa ProtonMail). Konti yubwenge yumukoresha ikoresha igenzura umukono kumurongo kandi ikora transaction niba umukono wemewe. Usibye kugenzura umukono, ni ngombwa no kugenzura ibyo

1. imeri yoherejwe kuva kuri imeri yumukoresha,
2. yoherejwe kuri aderesi imeri imeri kandi
3. ko imeri ikubiyemo ingingo iboneye (ikubiyemo Calldata cyangwa tx ibisobanuro).

Urugero

Alice yohereje imeri ikurikira kuri relayer:

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

Reba umutwe wa DKIM-Signature ? Numukono wakozwe nurufunguzo rwihariye rwa iCloud. Ibindi bisigaye bizasobanura:

1. Niki rwose cyashyizweho umukono nuwatanze imeri
2. Nigute ushobora kubona imeri itanga urufunguzo rusange
3. Nigute ushobora kugenzura umukono muri Noir

Umukono

Umukono wa DKIM washyizweho nuwatanze imeri isinya igice cyimitwe muburyo bukwiye kandi muburyo bwa Canonical. Reka turebe umutwe wa DKIM-Umukono:

 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==

Igizwe nurufunguzo-agaciro kamwe gatandukanijwe na semicolons. Ibice byingenzi ni: a= na b= . Reka tubice:

• a= ni algorithm ikoreshwa mu gusinya ubutumwa. Muri uru rubanza, ni rsa-sha256 .
• b= ni umukono ubwawo muri base64 kodegisi.

Ni iki cyashyizweho umukono neza?

Imirongo ya imeri itondekanye kandi yemewe mbere yo gusinya. Itondekanya ryimitwe isobanurwa na h= ibipimo byumutwe wa DKIM-Signature . Noneho imitwe ihindurwe murubanza ruto, ikibanza cyera cyakuweho, hanyuma gihujwe ninyuguti \r\n . Reka turebe imitwe mbere ya Canonicalisation:

Menya ko umutwe wa DKIM-Signature nawo ushyirwa mumitwe yemewe ariko ibura agaciro ka b= ibipimo. Gusa urufunguzo rurimo.

Iyo wohereje imeri, iCloud.com izasinya imitwe yemewe hamwe nurufunguzo rwihariye. Umukono noneho ushyirwa mumutwe wa DKIM-Signature . By'umwihariko muri b= ibipimo.

Utanga imeri urufunguzo rusange

Ibibazo 2:

1. Nigute ushobora kubona imeri itanga urufunguzo rusange?
2. Nigute ushobora kugenzura umukono muri Noir?

Niba urebye umutwe wa DKIM-Signature uturutse hejuru, uzabona ibipimo 2: d=icloud.com na s=1a1hai . Aba ni d omain hamwe s imeri itanga imeri. Turashobora kubona urufunguzo rusange mubaza inyandiko yihariye ya DNS: {s}._domainkey.{d} . Muri uru rubanza, tugomba kubaza 1a1hai._domainkey.icloud.com . Reka tubabaze dukoresheje dig itegeko:

Uru nurufunguzo rusange rwabatanga imeri ( iCloud.com ) rwanditse muri base64. Tuzayikoresha nyuma kugirango tumenye umukono muri Noir.

Inzira ya Noir

Bitewe n'imbogamizi zumuzunguruko wa ZK, tugomba gukoresha uburyo bunoze bwo gushyira mubikorwa RSA numubare munini utangwa nitsinda rya Noir: https://github.com/noir-lang/noir_rsa .

Shyira muri Nargo.toml:

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

Noneho, reka turebe umuziki wa Noir kugirango ugenzure:

 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) }

Nzasimbuka ibitumizwa hanze hanyuma wandike ibisobanuro kubugufi (ninde ubyitayeho, kopi-paste). Reka turebe ibipimo verify_email :

• headers : imitwe ya Canonicalized imitwe nka array ya bytes. Ifite uburebure butajegajega kandi igomba gupakirwa na 0 kurangiza
• headers_len : uburebure nyabwo bwimitwe
• pubkey_limbs & pubkey_redc_limbs : urufunguzo rusange rwabatanga imeri rwabigenewe kuri Noir
• signature : umukono wa imeri itanga kodegisi ya Noir

Mubikorwa byimikorere, tubanza guhindura umukono nurufunguzo rusange kumubare munini. Noneho dushyira imitwe ya Canonicalized imitwe hamwe na sha256 hanyuma tumenye umukono hamwe nurufunguzo rusange 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)

Niba igenzura ryagenze neza, imikorere igaruka true , naho ubundi igasubiza false .

Kuva kumurongo wibanze wa imeri kugeza Noir yinjiza

Noneho, ko dufite umuzunguruko wa Noir, nigute dushobora guhindura umurongo wa imeri mbisi kumurongo winjiye kumuzunguruko?

Reka duhere kumutwe. Nzakoresha mailparser mugusobanura imeri na dkim kugirango nkuremo imitwe yemewe. Koresha imeri:

 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 }; }

Noneho, gerageza:
