The process is detailed here.

User guide

Setting up XOR pads for decrypting icon data

 3DS_IconDecrypter 
 --genxor
 --iconcache="path to icon cache" 
 --unused_slots=X 
 --num_decrypt=Y 
 --decdata="path to dir with plaintext icons" 
 --xorpaddir="path to dir for output XOR pads"

• "X" - The number of icons that exist in the cache before the first icon you want to generate an XOR pad for.
• "Y" - The number of icons you want to generate an XOR pad for.

Decrypting Icons from cache

 3DS_IconDecrypter
 --decrypt
 --iconcache="path to icon cache"
 --unused_slots=X
 --num_decrypt=Y
 --xorpaddir="directory with XOR pads"
 --decdata="directory for outputing decrypted icons"

• "X" - The number of icons that exist in the cache before the first icon you want to decrypt.
• "Y" - The number of icons you want to decrypt.
