Class TPMS_RSA_PARMS

  • All Implemented Interfaces:
    TPMU_PUBLIC_PARMS, TpmMarshaller, TpmUnion
    public class TPMS_RSA_PARMS
extends TpmStructure
implements TPMU_PUBLIC_PARMS
    A TPM compatible with this specification and supporting RSA shall support two primes and an exponent of zero. An exponent of zero indicates that the exponent is the default of 216 + 1. Support for other values is optional. Use of other exponents in duplicated keys is not recommended because the resulting keys would not be interoperable with other TPMs.

    • Field Detail

      • symmetric

        public TPMT_SYM_DEF_OBJECT symmetric
        For a restricted decryption key, shall be set to a supported symmetric algorithm, key size, and mode. if the key is not a restricted decryption key, this field shall be set to TPM_ALG_NULL.

      • scheme

        public TPMU_ASYM_SCHEME scheme
        Scheme.scheme shall be: for an unrestricted signing key, either TPM_ALG_RSAPSS TPM_ALG_RSASSA or TPM_ALG_NULL for a restricted signing key, either TPM_ALG_RSAPSS or TPM_ALG_RSASSA for an unrestricted decryption key, TPM_ALG_RSAES, TPM_ALG_OAEP, or TPM_ALG_NULL unless the object also has the sign attribute for a restricted decryption key, TPM_ALG_NULL NOTE When both sign and decrypt are SET, restricted shall be CLEAR and scheme shall be TPM_ALG_NULL.
