fapi-config(5) to adjust Fapi parameters like the used cryptographic profile and TCTI or directories for the Fapi metadata storages.

fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys and operations of a specific TPM interaction like the name hash algorithm, the asymmetric signature algorithm, scheme and parameters and PCR bank selection.

Description

tss2_exportkey(1) - This command will duplicate a key and encrypt it using the public key of a new parent. The exported data will contain the re-wrapped key pointed to by the pathOfKeyToDuplicate and then the JSON encoded policy. Encryption is done according to TPM encryption schemes specified in the cryptographic profile (cf., fapi-profile(5)).
