In the browser, I'm using AES-256-CBC with 128bit IV & PBKDF2 to encrypt the mnemonic
"tell file snow green proof evil six squeeze budget various orbit clock"
with a password
with 30,000 rounds it's taking roughly 22 seconds. It feels too long, but I don't want to make it insecure.
Can I safely reduce the rounds to make it a bit faster? and if so what would be the minimum?
Could I get away with 10,000?
