Difference between "encrypted" and "decrypted" PKM files?

[DiamondSword]

Hi
I wanted to ask what the difference between .ek* and .pk* files are. Whenever I save a Pokémon file (ORAS as an example) it defaults to .pk6 but there's a drop-down list of file types available, and one of them is .ek6
Does this make any difference which file type I save my Pokémon as? I'm wondering if transferring the file to another save it would change things like the encryption constant, PID, memories, OT/HT data, markings etc
Thank you

The only difference is that one is encrypted, and the other one is decrypted (not encrypted). Encrypted data must be decrypted before checking specific properties of the Pokemon (like Species), but the game stores data in the encrypted form whenever it is not in use.

Decrypted data is human readable, while encrypted data is the state the game expects it to be in.
