@ -170,6 +170,7 @@ onion_address = base32(PUBKEY | CHECKSUM | VERSION) + ".onion"
- VERSION is an one byte version field (default value '\x03')
- ".onion checksum" is a constant string
- CHECKSUM is truncated to two bytes before inserting it in onion_address
- H() is the SHA3-256 cryptographic hash function
</pre>
Tor v3 addresses MUST be sent with the <code>TORV3</code> network ID, with the 32-byte PUBKEY part in the address field. As VERSION will always be '\x03' in the case of v3 addresses, this is enough to reconstruct the onion address.
