Constructors

constructor

Properties

alwaysAuthenticate

alwaysAuthenticate: boolean

if true, the user has to supply the PIN for each use (sign or decrypt) with the key. Default is false

alwaysSensitive

alwaysSensitive: boolean

true if key has always had the CKA_SENSITIVE attribute set to true

  • Must not be specified when object is created with C_CreateObject.
  • Must not be specified when object is generated with C_GenerateKey or C_GenerateKeyPair.
  • Must not be specified when object is unwrapped with C_UnwrapKey.

class

class: ObjectClass

Object class (type)

decrypt

decrypt: boolean

true if key supports decryption

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.
  • Default value is token-specific, and may depend on the values of other attributes.

derive

derive: boolean

CK_TRUE if key supports key derivation (i.e., if other keys can be derived from this one (default CK_FALSE)

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.

Returns

boolean

endDate

endDate: Date

End date for the key (default empty)

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.

extractable

extractable: boolean

true if key is extractable and can be wrapped

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.
  • Attribute cannot be changed once set to false. It becomes a read only attribute.
  • Default value is token-specific, and may depend on the values of other attributes.

handle

handle: Buffer

ID of PKCS#11 object

id

id: Buffer

Key identifier for key (default empty)

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.

label

label: string

Description of the object (default empty)

lib

lib: PKCS11

PKCS#11 module

local

local: boolean

CK_TRUE only if key was either * generated locally (i.e., on the token) with a C_GenerateKey or C_GenerateKeyPair call * created with a C_CopyObject call as a copy of a key which had its CKA_LOCAL attribute set to CK_TRUE

  • Must not be specified when object is created with C_CreateObject.
  • Must not be specified when object is generated with C_GenerateKey or C_GenerateKeyPair.
  • Must not be specified when object is unwrapped with C_UnwrapKey.

mechanism

mechanism: KeyGenMechanism

Identifier of the mechanism used to generate the key material.

  • Must not be specified when object is created with C_CreateObject.
  • Must not be specified when object is generated with C_GenerateKey or C_GenerateKeyPair.
  • Must not be specified when object is unwrapped with C_UnwrapKey.

modifiable

modifiable: boolean

true if object can be modified. Default is false

neverExtractable

neverExtractable: boolean

true if key has never had the CKA_EXTRACTABLE attribute set to true

  • Must not be specified when object is created with C_CreateObject.
  • Must not be specified when object is generated with C_GenerateKey or C_GenerateKeyPair.
  • Must not be specified when object is unwrapped with C_UnwrapKey.

private

private: boolean

true if object is a private object and false if object is a public object. Default value is token-specific, and may depend on the values of other attributes of the object.

sensitive

sensitive: boolean

true if key is sensitive

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.
  • Attribute cannot be changed once set to CK_TRUE. It becomes a read only attribute.
  • Default value is token-specific, and may depend on the values of other attributes.

session

session: Session

PKCS#11 session

sign

sign: boolean

true if key supports signatures where the signature is an appendix to the data

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.
  • Default value is token-specific, and may depend on the values of other attributes.

signRecover

signRecover: boolean

true if key supports signatures where the data can be recovered from the signature

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.
  • Default value is token-specific, and may depend on the values of other attributes.

startDate

startDate: Date

Start date for the key (default empty)

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.

subject

subject: Buffer

DER-encoding of the key subject name (default empty)

  • May be modified after object is created with a C_SetAttributeValue call, or in the process of copying object with a C_CopyObject call. However, it is possible that a particular token may not permit modification of the attribute during the course of a C_CopyObject call.
