The Import Key (OPM, QC3IMPKY; ILE, Qc3ImportKey) API encrypts a key under the specified master key.
The key to be encrypted under a master key. This can be a symmetric key or a PKA private key.
Length of the key string specified in the key string parameter.
An indicator specifying if the key string parameter is in encrypted form.
| 0 | Clear. The key string is not encrypted. |
| 1 | Encrypted. The key string is encrypted. The key-encrypting key context token and key-encrypting algorithm context token parameters are used to decrypt the key string before encrypting it under the specified master key. |
The key context token specifying the key for decrypting the key string parameter. If the key string parameter is not encrypted (key form parameter is 0), this parameter must be set to blanks or the pointer to this parameter set to NULL.
The algorithm context token specifying the algorithm for decrypting the key string parameter. If the key string parameter is not encrypted (key form parameter is 0), this parameter must be set to blanks or the pointer to this parameter set to NULL.
The master key under which the specified key will be encrypted. For more information about master keys, refer to Cryptographic Services Master Keys. The master key IDs are
| 1 | Master key 1 |
| 2 | Master key 2 |
| 3 | Master key 3 |
| 4 | Master key 4 |
| 5 | Master key 5 |
| 6 | Master key 6 |
| 7 | Master key 7 |
| 8 | Master key 8 |
This parameter specifies the functions that cannot be used with this key. The values listed below can be added together to disallow multiple functions. For example, to disallow everything but MACing, set the value to hex 11. This value should be saved along with the encrypted key value because it will be required when the encrypted key value is used on an API.
| 0 | No functions are disallowed. |
| 1 | Encryption is disallowed. |
| 2 | Decryption is disallowed. |
| 4 | MACing is disallowed. |
| 8 | Signing is disallowed. |
The key verification value of the master key that was used to encrypt
the key. This value should be saved along with the encrypted key value.
When the encrypted key value is used on an API and the KVV is supplied, the
API will be able to determine which version of the master key should be used
to decrypt the key.
The area to store the imported key.
The length of the imported key parameter.
To ensure sufficient space, specify an area as large as the clear key string
length plus space for padding. The key string will be
encrypted using AES with a 32-byte block size. Therefore, the clear key string
length will always be padded out to the next 32-byte boundary before encrypting.
The length of the imported key returned in the imported key parameter.
If the length of area provided for the imported key is too small, an error will be generated and no data will be returned in the imported key parameter.
The structure in which to return error information. For the format of the structure, see Error Code Parameter.
