eth2-keystore-converter

Convert Eth2 EIP-2335 scrypt keystores to pbkdf2 keystores (and vice-versa).

Usage

Converting a scrypt keystore to pbkdf2 using stdin/stdout

cat keystore-scrypt.json \
  | eth2-keystore-converter -p $(cat keystore-scrypt.txt) \
  > keystore-pbkdf2.json

Converting a pbkdf2 keystore to scrypt using options

eth2-keystore-converter \
  -f keystore-pbkdf2.json \
  -p $(cat keystore-pbkdf2.txt) \
  -c scrypt \
  -o keystore-scrypt.json

Motivation

The scrypt formatted keystores load slower and require a lot more memory than pbkdf2 formatted keystores which load almost instantly.

Thus, converting on the fly all keystores to pbkdf2 makes it easier to operate eth2 validators at scale and reduce computing resources.
