- Private Keys are represented internally as 32 element Uint8 Arrays.
- Represented in text form as 64 digits of hexadecimal.
- cjdns does not currently require anything more than the private key at launch time. It derives the public key and ipv6 after loading the private key to avoid errors.
- The public key is entirely dependent on the privateKey.
- Represented internally as another 32 element Uint8 Array.
- Represented in text form as a 52 character string of cjdns' base32 encoding.
- cjdns base32 consists of the following characters:
- 0123456789bcdfghjklmnpqrstuvwxyz
- Any string matching the following regex is invalid cjdns base32
- An ipv6 is the hash of the hash of the public key, encoded in hexadecimal, and trimmed to the first 32 characters, with colons inserted between every two byte section.
- Password are (nearly) arbitrary text strings.
- Their length is variable.
- There are only a few banned characters:
- newlines (\n)
- quotation marks (")
- backticks (`)
- backslashes ()
- spaces ( )
- tabs (\t)
- curly braces ({,})
<@cjd> be careful of non a-zA-Z0-9_
- There may be more invalid characters, please let us know if you find any!
- They can be generated in bash with the following one-liner:
cat /dev/urandom | strings | head -n 50 | tr -d '\n"`\\ \t' | head -c 50 && echo OR tr -cd '[:alnum:]' < /dev/urandom | fold -w32 | head -n20`
- On OpenWrt, the following shorter one-liner is used:
tr -cd 'A-Za-z0-9' 2> /dev/null < /dev/urandom | head -n 20
