Just laying out a garden of information on repeat.<\/p>\n\n\n\n\n\n\n\n

I run this website under a tor address with a basic set of urls posted here<\/a>. I decided to see if I could make some sense of things.<\/p>\n\n\n\n

In order to generate a custom ed25519 key there is oniongen-c<\/a>, horse25519<\/a>, or mkp224o<\/a>. I used mkp224o since it was easier to benchmark.<\/p>\n\n\n\n

I wanted to start from the bare bones of learning ed25519, so reading up from ed25519.cr.yp.to<\/a> was a good first step.<\/p>\n\n\n\n

Secondly its’ fairly easy to generate an ed25519 key via unixtutorial.org<\/a>.<\/p>\n\n\n\n

$ ssh-keygen -t ed25519 -C \"derp@derp.net\"\nssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIBh+xO3mGMUtGUNQ\/5oWwfUOASBKh4GG6ud5iJZFGCYz derp@derp.net\n$ echo -n \"AAAAC3NzaC1lZDI1NTE5AAAAIBh+xO3mGMUtGUNQ\/5oWwfUOASBKh4GG6ud5iJZFGCYz\" | base64 -d | hexdump -C\n00000000  00 00 00 0b 73 73 68 2d  65 64 32 35 35 31 39 00  |....ssh-ed25519.|\n00000010  00 00 20 18 7e c4 ed e6  18 c5 2d 19 43 50 ff 9a  |.. .~.....-.CP..|\n00000020  16 c1 f5 0e 01 20 4a 87  81 86 ea e7 79 88 96 45  |.....

After creating a key it was trivial to determine where my key could be created for a new onion domain, unlit3rat54udo35sr6s3gc6wsgux35oeyhj4ndcukdtedw5kqklkdyd.onion:<\/p>\n\n\n\n
$ hexdump -C hs_ed25519_public_key\n00000000  3d 3d 20 65 64 32 35 35  31 39 76 31 2d 70 75 62  |== ed25519v1-pub|\n00000010  6c 69 63 3a 20 74 79 70  65 30 20 3d 3d 00 00 00  |lic: type0 ==...|\n00000020  a3 56 89 ee 20 xx xx xx  xx xx xx xx xx xx xx xx  |.V.. xxxxxxxxxxx|\n00000030  xx xx xx xx xx xx xx xx  xx xx xx xx xx xx xx xx  |xxxxxxxxxxxxxxxx|\n\npublic key: a3 56 89 ee 20 xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx<\/code><\/pre>\n\n\n\n
Now that I’ve found the public key I get to manually convert it to visually verify that things are what they say they are:<\/p>\n\n\n\n
