information may follow in some future versions.
10. Field: User-ID. The value is quoted like a C string to avoid
control characters (the colon is quoted "\x3a").
11. Field: Signature class
12. Field: Key capabilities:
e = encrypt
s = sign
c = certify
A key may have any combination of them. The primary key has in
addition to these letters, uppercase version of the letter to
denote the _usable_ capabilities of the entire key.
More fields may be added later.
