Decrypted is the term given to the upgraded uncroaked (or "popped again") Wanda creates after attuning to the Arkenpliers. Decrypt is used as a verb (he was decrypted), an adjective (a decrypted unit), and a noun (decrypted retain their stats), similar to the usage of uncroaked.
Unlike uncroaked units, decrypted units do not decay. Furthermore they appear to be fully physically alive with intact biological functions, lacking the physical evidence of the trauma that croaked them.
Decrypted are loyal to the tool wielder, regardless of past allegiances, but still remember their past loyalties, any information they knew in the past, and loves. They are also resistant (but not entirely immune) to Turnamancy, although the exact nature of their (in)ability to turn is unclear. They're not entirely immune to turning, though, as Ossomer demonstrated; this may be a factor of personal physical distance from the Arkenpliers.
Decrypted units have zero upkeep cost and retain more of their pre-death strength, if not full strength, than uncroaked. It is unknown whether they actually need to eat rations, but they are certainly capable of it. It is also unknown whether rations pop for them normally, but they do at least pop for Decrypted units who are prisoners.
Units heal all their lost hits and are cleansed immediately upon decrypting. Their livery also changes to whatever their attuned master wishes, just like uncroaked. After a short bit of disorientation upon waking they are able to immediately start fighting. Decrypted still are able to gain experience.
Decrypted Natural Allies are units of the side of the wielder of the Arkenpliers, and don't count as a separate tribe, so if all members of a Natural Allies tribe are croaked, not even Decrypting them can allow to build more units of their former tribe.
Though decrypted units will presumably tell Wanda anything relevant that has happened to them, Wanda is capable of directly accessing the senses of certain units with natural thinkamancy (like Archons).
In addition to livery, decryption can alter the signamancy of a unit beyond their uniforms. Units without clothing will have their markings changed, such as wiener-rammers turning all black or dwagons gaining black stripes. Casters with ashen skin may be restored to their original pigmentation.
It is worth noting that Decrypted can turn of their own volition, unlike Dolls. We have seen this when Ossomer turned during the Siege of Spacerock,Erf-b2-p73 and again when Marie turned to Jillian in ICFYS.Erf-b3-p280
Newly decrypted seem to gain some degree of loyalty to Wanda (personally, not to her side), and may suffer a major mental attitude adjustment (e.g. "You were correct, of course. Royalty is obsolete."). This could be due to a change in the unit's Natural Thinkamancy or a choice made by Wanda at the time of decryption. Otherwise, the unit retains all of its previous stats, abilities, and levels, but it may suffer a demotion if it was of a high rank and that position is already occupied by another Unit.
It is unknown as of yet exactly how the Arkentools do what they do. It seems that they give Wanda an advanced form of Croakamancy, but it is a theory that it acts like a caster link, allowing Wanda to use a Croakamancy/Healomancy/Turnamancy spell to make the decrypted. Another possibility: could it be a form of Retconjuration, allowing Wanda to remake the croaked unit as she sees fit?
If, as has been suggested, the Arkenpliers extend Wanda's Croakamancy into the life element, could there be another stage above uncroaked and decrypted, one of true resurrection?
Real World References
In the real world, encryption is the hiding (protection) of information by turning it into a seemingly random sequence of symbols; decryption is the reverse process, turning the seemingly-random symbols back into meaningful information. This parallels the process of taking a useless corpse and turning it (back) into a useful creature.
The term decryption is sometimes also used for extracting desired content from protected sources (such as DVDs, music files and e-books). In this case, Wanda might have gained the ability to effectively remove the DRM from enemy units, allowing her to raise them without penalties and under her control.
The term is also a pun on crypt, as in "taking the unit out of the crypt".
Being "popped again" is certainly a joking reference to the Christian concept of being born again, as being popped is the Erfworlders' version of being born, and Ansom, the one who coined the phrase, converted to Toolism upon being popped again and proceeded to evangelize his new faith.
