# Generate SHA-384 hash for RSA and ECDSA 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. To generate the SHA-384 hash of the root certificate, run the following command: > > > openssl dgst -sha384 qpsa_rootca.cer >sha384rootcert.txt > Copy to clipboard ## Next steps - To ensure the authenticity and integrity of software images, see [Sign images](https://docs.qualcomm.com/doc/80-70018-11/topic/sign-the-images.html#sign-the-images). - To verify that the software hasn’t been tampered with and is from a trusted source, see [Generate signed sec.elf image](https://docs.qualcomm.com/doc/80-70018-11/topic/generate-signed-sec-elf-image.html#generate-signed-sec-elf-image).
