    So we can recover pubkey binary (but no marker; marker is depends on OEMCreatorID and calculating it requires to find "secret" key of RSA, which takes huge time) from certificate if it is missing.
    Then, can we recover Certificate from pubkey if it is missing inversely?


    P.S. What are other elements of SLIC certificates , such as <signaturevalue> ... </signaturevalue> and <Modulus>...</Modulus> ?
    Thanks in advance.
