about

kybermail is an anonymous by design email system.

your private key is your secure login. it's needed by the system to decrypt messages sent to your public key. keep it safe, and do not share it with anyone.

your public key is shared with others, to send and receive messages. the two keys are linked, but cannot be reverse engineered.

think of your public key as a username, and your private key as a password.

the CRYSTALS-Kyber-768 algorithm is utilized for cryptography, selected by NIST as the primary standard for government and banking systems in 2022. it's post-quantum, specifically designed to defend against brute force attacks which use quantum computing.

there is zero user knowledge stored. no ip logging, metadata, tracking, profiling, or analytics. keys are hashed with SHA3-256 before being added to the database, raw keys never touch the server.

all files and messages are padded to a standard size and scrubbed of metadata. timing patterns are normalized. session data is memory-only and discarded immediately.

perfect anonymity would require every user to use identical hardware running identical software.

remember "harvest now, decrypt later". assume everything sent is logged, and can eventually be accessed by a government agency.

do not use this service for illegal materials. flag any abuse using the report icon.
