Hello, I have used in the past curl with openssl 1 to authenticate to a remote server using keys stored in the TPM. The TPM2 tss engine (https://github.com/tpm2-software/tpm2-tss-engine) enabled the TPM integration with openssl and with curl.
Unfortunately, Ubuntu 22.04 made the switch to openssl 3 and the command I was used to run, that was leveraging the –engine option, is not working anymore. A new project called TPM2-openssl (https://github.com/tpm2-software/tpm2-openssl) provides the integration between the TPM 2 and Openssl 3 but only via the new openssl -provider<https://www.openssl.org/docs/manmaster/man1/openssl.html> option. Does curl support those new openssl 3 providers? If not, is there an alternative way to use curl with the TPM? Thanks. Best regards, Matteo
