Migration to Tor addresses version 3
The first release of Blacknet shipped with support for Tor addresses v2.
The Tor Project has planned to retire it in 2021.
The v3 update switches cryptographic algorithms and brings other improvements. Cryptographic hash switched from SHA-1 to SHA-3. Digital signature switched from RSA-1024 to Ed25519. Key exchange switched from Diffie-Hellman to Elliptic-curve Diffie-Hellman.
Address length changed from 16 characters to 56 characters. For example,
zwdpzg2tzsqjinlb.onion is version 2,
q4xgfyeusviqe3l25ogmgbcxc4c34laaqshurjtf6bxjub45mxumo2id.onion is version 3.
Blacknet will start migration in version 0.3.
