Hello, I am learning about encryption / decryption using Fapi. For that purpose, I create a key using tss2_createkey and use tss2_encrypt / tss2_decrypt (and their Fapi equivalents). tss2_ createkey has the argument -a, --authValue to set up a decryption password. With tss2_encrypt I generate the cipher text. The problem is with the decryption process. When I decrypt with tss2_decrypt I got asked for that authValue. If it is given correctly it decrypts the cipher text. However, Fapi_Decrypt will fail throwing an authorization error. I was wondering how to programmatically enter the authValue? Fapi_Decrypt has no arguments to pass it. Maybe through the FAPI_CONTEXT? Using TPM2-TSS v. 2.4.x TPM2-TOOLS v. 4.X Thank you for any possible help.
