Cryptarch

A Cryptarch, or "Crypto-archaeologist" is the designation for an individual who studies the properties of encoded matter, known as Engrams. These individuals can unlock the patterns stored within Engrams, allowing for the item encoded within the pattern to be spontaneously created in a process known as "decoding". There are two Cryptarchs; Master Rahool in The Tower, and Master Ives in the Vestian Outpost. Besides selling and decoding engrams, the cryptarch will also buy any Axiomatic Beads, House Banners, Network Keys, and/or Silken Codex that the player is carrying for 200 glimmer each.

Reputation
Reputation is the Cryptarch's skill in identifying, decrypting and decoding Engrams brought in by Guardians. Reputation is gained by either buying Engrams from him (which he then decodes) or by providing him with Engrams to decode, which are found during the Guardian's travels. As a Guardian decodes more Engrams his/her Reputation increases. This is represented by a diamond-shaped meter which surrounds the Crypto-archaeology symbol located to the left of the Cryptarch symbol on his inventory screen. Each time this meter fills completely, the Cryptarch's Rank increases by 1. The higher the number, the greater the Cryptarch's skill at unlocking any Encrypted Engrams the player brings to him. Certain Encrypted Engrams require the Cryptarch to be of a particular rank before they can be purchased from him (though he does not sell any engrams higher than rare quality, and even then only seldom).

After rank 3, the Cryptarch will start rewarding players with engram packages with each new level. These packages normally contain rare engrams, but have a chance of producing legendary engrams.
