# Introduction

Challenges (CHL commands) require a key pair (for the QRY command) to be solved.

The following is a list of valid key pairs.

If you know of a key pair not on this list, or just the Public Key associated with a client, feel free to contact me.

Format of the Public Keys (except the first msmsgs@msnmsgr.com one) seems to be "PROD", then four digits, the first being a 0, then 8 random characters. The four digits seem to increase by at least 1 every time a new key pair is made.

Private keys seem to have a format of 16 random characters.

Random characters in both cases will match the regular expression of [A-Z0-9{}!@*%_?$#].

# Old key pairs

Only in MSNP6 to MSNP10.

# New key pairs

Since MSNP11.
