I just got the OpenSSL ocsp tool option -rmd for specifying the digest algorithm in signature.
This option is described at the below page, https://www.openssl.org/docs/manmaster/man1/openssl-ocsp.html Just out of curiosity, why isn't it at the following man page? https://www.openssl.org/docs/man1.1.1/man1/ocsp.html Though this option is supported by 1.1.1 series.
