What Hacker News says?
I came across a blogpost describing this workflow recently and I'm curious to hear HN opinions about it. Any pitfalls? https://matthewdowney.github.io/encrypting-keys-in-clojure-a... 1. Generate a new set of API keys. 2. Read my encrypted map of keys from disk, decrypt it with a passphrase, assoc in the new key & secret, encrypt it again, and write it to disk. 3.
