This posting http://forum.bittorrent.com/topic/25823-generate-encrypted-read-only-secret-without-api-key has the best description I've read yet of various key formats, including the prefix character.

GreatMarko, I am not sure secrets are as you describe. For example, I can generate a secret like "ACEAYC457A2U8VQBNMEN0X15779PVMU5Q", and while it is "A" followed by 32 random characters, it doesn't appear to be a valid secret.
