How to unlock the Decryptologist achievement in Destiny - Definitive Guide
Considering this is a drop-based achievement this could take you a few hours to a few days. However if you buy engrams from the merchant I cannot confirm if they count towards this achievement. That said I would say from my experience it seemed to help.
*EDIT 1: You CAN buy engrams from the merchant for progress on this achievement. Thanks to Vermigs for confirmation *
If you're desperate for the achievement all I can advise is to go to a low level area (Earth, where the broken ship is to the north of where you land in Patrol is a good spot) and farm enemy kills. If you're a much higher level they'll fall like rain and you may get a few Engrams.
Hope this helps!
Also; for those having trouble unlocking glitchy achievement do this:
Press the Menu button RB over to settings, highlight Log Out and choose Switch Profile (not Change Character). This will take you back to the game start screen, and once you press A, it will ask you to choose your Xbox Live profile.
Choose your profile and then choose your character from the character select screen. Any achievements that should have been unlocked will then unlock.

Sorry the english is not my language.
Good play !
i.e., find an Engram @ level 15, decrypt it @ level 20 for level 20 gear. recommended for rarer engrams.
To get this achievement simply decrypt a total of 25 engrams. You can either play the game normally until you are awarded 25 engrams and then take them to the Cryptarch at the Tower to decode, OR, you may purchase engrams directly from the Cryptarch. Once your Cryptarch has decoded a total of 25 engrams the achievement will unlock.
*** DESTINY GLITCHED ACHIEVEMENTS FIX ***
Destiny Achievements are VERY glitchy. In order to unlock achievements
you have already met the requirements for you must cycle your connection
to the Destiny servers. The easiest way to do this is as follows;
ENTER the game > Press START > LOGOUT > SWITCH PROFILE >
CHOOSE your GAMERTAG > SELECT your CHARACTER > POP goes the cheevo
Hope this helps!
Happy gaming

Engrams are items that can be found or purchased, and subsequently decrypted by Master Rahool in the Tower to award a piece of loot and rep toward the Cryptarch faction. You should have no issue getting 25 through the main story via drops alone, but it will easily come while farming for the end game Raid achievements, so don't waste your glimmer purchasing any.
Engrams will drop randomly from enemies, but some can be purchased from either Cryptarch (for various amounts of Legendary Marks) or from Xur (for various amounts of Strange Coins). Any combination of colors of white (Common), green (Uncommon), blue (Rare), purple (Legendary or Sublime), or yellow (Exotic, normal or Legacy) will contribute to the count. This will come over time, so there is no need to grind this out.
