I have a 2018 email to my self entitled "methwal" that is definitely not about amphetamines.

It includes:

An approximately 50 character alphanumeric string

A password hint I recognize

A file attachment (long alphanumeric strings replaced with …)

{"version":3,"id":"…","address":"…","Crypto":{"ciphertext":"…","cipherparams":{"iv":"f0ff3f6ce14c78830f7564fe947c5181"},"cipher":"aes-128-ctr","kdf":"scrypt","kdfparams":{"dklen":32,"salt":"…","n":1024,"r":8,"p":1},"mac":"…"}}

Any suggestions on how to get at this?

Thanks!
