Description

This function extends AAL2GenResetSataticPasswordCmd. With this function, you can address the HSM storage key by name and to specify an initial vector. The initial vector is used during the 3DES/AES encryption of the sensitive authenticator application BLOB data.

The Digipass static PIN management on the HSM is identical to the functionality available with the Authentication Suite Server SDK Software Digipass Management Service. For information on the associated functions, refer to the Authentication Suite Server SDK C-C++ Programmer's Guide.

This function must be used with the post-HSM API AAL2ProcResetStaticPasswordRpl.

Parameters

  Table: Parameters (AAL2GenResetStaticPasswordCmdEx)
TypeNameUseDescription
aat_byte *CmdO

426 bytes that serialize the RESET STATIC PASSWORD command type and the input data to the reset static password function on the HSM:

  • Command type - 2 bytes
  • An authenticator application BLOB - 192 bytes
  • Runtime parameters - 80 bytes
  • StorageKeyName - up to 128 characters
  • InitialVector - 8 bytes

Plus 8 bytes for Authentication Suite Server SDK internal use.

aat_int32 *CmdSizeI/O

On entry, this parameter contains the size of the Cmd buffer.On exit, this parameter contains the length of the Cmd message.

TDigipassBlob *DPDataIauthenticator application BLOB.
TKernelParms *CallParmsI

Structure of runtime parameters to use during this function call.

aat_ascii *aStorageKeyNameInI

String of up to 128+1 characters, left-justified, null-terminated, or right-padded with spaces. This is the label of the HSM storage key used to encrypt the sensitive Digipass application BLOB data.

aat_ascii *aIVInI

String of 16 hexadecimal characters, left-justified, null-terminated, or right-padded with spaces. This is the initial vector used to encrypt the sensitive authenticator application BLOB data.
