openssl dgst

OpenSSL command to generate digest values and perform signature operations.

More information.

Calculate the SHA256 digest for a file, saving the result to a specific file:

openssl dgst -sha256 -binary -out {output_file} {input_file}

Sign a file using an RSA key, saving the result to a specific file:

openssl dgst -sign {private_key_file} -sha256 -sigopt rsa_padding_mode:pss -out {output_file} {input_file}

Verify an RSA signature:

openssl dgst -verify {public_key_file} -signature {signature_file} -sigopt rsa_padding_mode:pss {signature_message_file}

Sign a file using and ECDSA key:

openssl dgst -sign {private_key_file} -sha256 -out {output_file} {input_file}

Verify an ECDSA signature:

openssl dgst -verify {public_key_file} -signature {signature_file} {signature_message_file}
