4 years ago The reason for sudo is probably because you don't have read/write permissions for /dev/tpmrm0.
The owner-auth problem is interesting. Have you tried version 1.1.0 yet ? https://github.com/tpm2-software/tpm2-tss-engine/releases/tag/v1.1.0
Hi I have configured and make install everything as per the link tpm2-tss-engine, tpm2-tss, tpm2-tools for tpm2-tss when i make install i am getting warning messages warning: relinking 'src/tss2-tcti/libtss2-tcti-swtpm.la' ...etc
I have configured tpm2-tss-engine openssl.conf.sample
openssl_conf = openssl_init
[openssl_init] engines = engine_section
[engine_section] tpm2tss = tpm2tss_section
[tpm2tss_section] engine_id = tpm2tss
dynamic_path = /usr/lib/x86_64-linux-gnu/engines-1.1/libtpm2tss.so
default_algorithms = RSA
,ECDSA
init = 1 SET_TCTI = device:/dev/tpmrm0 SET_OWNERAUTH = 123
SET_PARENTAUTH =
[req] distinguished_name = subject
[subject]
prompts and defaults here
Next: When i issue the command openssl engine -t -c tpm2tss i works And i can create rsa key using command tpm2tss-genkey -a rsa rsa.tss But when i issue command
Without sudo openssl req -new -x509 -engine tpm2tss -key rsa.tss -keyform engine -out rsa.crt It prompts some question i entered the next is below error i am getting but crt file not created
