Enter a Seal ID, or upload your copy. Both work without an account.

— OR —

File server par save nahi hoti. Sirf uska SHA-256 nikaal kar hamare records se milaya jaata hai, phir file turant delete ho jaati hai.

Integrity — file byte-for-byte wahi hai jo seal hui thi.
Issuer — signature Fortax ke certificate se hai.
Time — digest OpenTimestamps ke zariye public Bitcoin ledger par anchor hota hai, jise koi control nahi karta.

Aur ye kya prove nahi karta. Fortax ka root certificate self-signed hai — kisi public CA ne use cross-sign nahi kiya. Iska matlab Adobe Reader jaisa koi tool khud-ba-khud green tick nahi dikhayega; yahi page trust anchor hai. Cryptographic guarantee wahi hai, par issuer ka naam Fortax ka apna daawa hai. Sealed file ke andar kya likha hai uski sachai par ye kuch nahi kehta — sirf itna ki wo badla nahi gaya.
