# Generate SHA-384 hash for RSA and ECDSA

Source: [https://docs.qualcomm.com/doc/80-70015-11/topic/generate-sha-384-hash-for-rsa-and-ecdsa.html](https://docs.qualcomm.com/doc/80-70015-11/topic/generate-sha-384-hash-for-rsa-and-ecdsa.html)

The SHA-384 hash is crucial in cryptographic applications for several reasons,
        including enhancing security strength, creating digital signatures, ensuring compliance with
        standards, and future-proofing.

1. To generate the SHA-384 hash of the root certificate, run the following
                    command:

        openssl dgst -sha384 qpsa_rootca.cer >sha384rootcert.txtCopy to clipboard
2. Use Sectools to create the leaf (also known as the attestation) certificate,
                    which is the final certificate in the chain.
