Key argument in computer encryption process (6)
I believe the answer is:
escrow
'computer encryption process' is the definition.
I can't judge whether this definition defines the answer.
'key argument' is the wordplay.
'key' becomes 'esc' ('Escape' key on a computer keyboard).
'argument' becomes 'row' (to row is to argue).
'esc'+'row'='ESCROW'
'in' is the link.
Can you help me to learn more?
(Other definitions for escrow that I've seen before include "back-up security" , "conditional execution of deed" , "fund held in trust?" , "document held by third party" , "Conditional deed held by third party" .)
