Parse RSA/ECDSA public key PEM into ASN1 JSON representation in pure bash

Parse PEM public keys into JSON

openssl already provides two ways of reading public keys in PEM format:

  • openssl ec -pubin -text -noout -in key.pem
  • openssl asn1parse < key.pem

Unfortunately, both provide text output which is hard to parse and use in an automated manner. This script provides a third way, and the output is structured JSON, using pure bash. See examples below.
