- In the few places where we wrap errors, use the new Go 1.13 "%w"
construction instead of %s or %v.
- Where we create errors with constant strings, consistently use
errors.New and not fmt.Errorf.
- Remove capitalization from errors in the few places where we had that.
A potential practical use is to encode a short version of the hostname
at the beginning of the device ID.
For example:
jb@syno:~/s/g/s/s/c/stvanity $ stvanity abc
Want 15 bits for prefix "ABC", about 3.3e+04 certs to test (statistically speaking)
Found ABCFPWS-JKDIFV3-E5IUAQW-DK53WVR-HY7XWBS-56H33GR-CJQI67Q-VGXRMAW
Saved to cert.pem, key.pem
jb@syno:~/s/g/s/s/c/stvanity $ stvanity $(hostname)
Want 20 bits for prefix "SYNO", about 1e+06 certs to test (statistically speaking)
Trying 554 certs/s, tested 8307 so far in 15s, expect ~32m total time to complete
Trying 543 certs/s, tested 16277 so far in 30s, expect ~32m total time to complete
...
The rest is just a matter of patience.
jb@syno:~/s/g/s/s/c/stvanity $ stvanity syncthing
Want 50 bits for prefix "SYNCTHI-NG", about 1.1e+15 certs to test (statistically speaking)
Trying 529 certs/s, tested 7941 so far in 15s, expect ~67443 years total time to complete
