    PUT ASYMMETRIC KEY

    Import an Asymmetric Key.

    Description

    Import an Asymmetric Key into the device.

    Shell Example

    Store an RSA key from key.pem into the device:

    yubihsm> put asymmetric 0 0 rsakey 1 sign-pkcs key.pem
Stored Asymmetric key 0x1e15

    Protocol Details

    Command

    Tc = 0x45

    Lc = 2 + 40 + 2 + 8 + 1 + LP1 { + LP2 }

    Vc = I || L || D || C || A || P1 { || P2 }

    The key parameters vary according to the chosen algorithm. Each parameter has a fixed length and the order is compulsory.

    I := Object ID of the Asymmetric Key (2 bytes)

    L := Label (40 bytes)

    D := Domains (2 bytes)

    C := Capabilities (8 bytes)

    A := Algorithm (1 byte)

    P1 :=

    For RSA: secret prime p (128, 192 or 256 bytes)

    For ECC: private key integer d (32, 48, 64 or 66 bytes)

    For EDC: private key integer k (32 bytes)

    P2 :=

    For RSA: secret prime q (128, 192 or 256 bytes)

    For ECC: NOT DEFINED

    For EDC: NOT DEFINED

    Response

    Tr = 0xc5

    Lr = 2

    Vr = I

    I := ID of created Object (2 bytes)
