alias-key bởi alias-key

alias-key is a tool that generates email aliases for any purpose. Its main strength comes from being able to secure each alias with the signature alias-key — Unique per service, always reproducible from the same inputs, and unpredictable to anyone who doesn't have your secret key.

Why use it?
Usability — one-click copyable aliases on the fly for any purpose.
Privacy — give every service a different address, so you know exactly which one leaked if you start receiving spam.
Security — treat your aliases like passwords; without your key an attacker cannot enumerate or predict your addresses.
Traceability — validate any address against all your profiles to verify it's an alias you created and identify which service it belongs to.

How to use it
1. Go to Auth and set a secret HMAC key. Back it up somewhere safe — losing it means losing the ability to verify or reproduce your aliases.
2. Add your email domains in the Domain block (e.g. mydomain.com).
3. Enter a name in the alias-name block for whatever the alias will be used for (e.g. github, amazon). The URL parser in the alias-name block can extract a name from a pasted URL.
4. Optionally enable alias-name encryption via the lock icon — the name becomes an opaque ciphertext in the alias, recoverable only with your key.
5. Adjust the block pipeline — add, remove, edit and reorder blocks to control the alias structure. Use the three dotted button between the draggable blocks and the domain block to add new blocks.
6. Configure the hmac-input to control what feeds the cryptographic function.
7. The alias is generated live at the top. Regenerate random blocks or copy the alias to the clipboard using the neighboring buttons.
8. Use profiles to maintain separate configurations, e.g. one per identity or use case. Use export/import to transfer the full profile configuration to other devices.
9. To identify an alias later, paste it into the Verify field. If needed, the ambiguity solver lets you manually or automatically resolve the correct interpretation.
10. Every copied alias is added to the alias log. Clear it or download the full log as a .tsv file as you please.
