Hyperledger Fabric SDK for node.js

Class: CryptoSuite_ECDSA_AES

CryptoSuite_ECDSA_AES

The module:api.CryptoSuite implementation for ECDSA, and AES algorithms using software key generation. This class implements a software-based key generation (as opposed to Hardware Security Module based key management)

new CryptoSuite_ECDSA_AES(keySize, hash)

constructor
Parameters:
Name Type Description
keySize number Key size for the ECDSA algorithm, can only be 256 or 384
hash string Optional. Hash algorithm, supported values are "SHA2" and "SHA3"

Methods

decrypt()

This is an implementation of module:api.CryptoSuite#decrypt To be implemented.
Overrides:

deriveKey()

This is an implementation of module:api.CryptoSuite#deriveKey To be implemented
Overrides:

encrypt()

This is an implementation of module:api.CryptoSuite#encrypt To be implemented.
Overrides:

generateEphemeralKey()

Generate an ephemeral key.
Inherited From:
Overrides:
Throws:
Will throw an error if not implemented
Returns:
An instance of the Key class
Type
module:api.Key

generateKey(opts)

Generate a key using the options in opts. If the opts.ephemeral parameter is false, the method, in addition to returning the imported Key instance, also persists the generated key in the key store as PEM files that can be retrieved using the getKey() method
Parameters:
Name Type Description
opts KeyOpts Optional
Inherited From:
Overrides:
Throws:
Will throw an error if not implemented
Returns:
Promise for an instance of the Key class
Type
module:api.Key

getKey(ski)

Returns the Key this implementation associates to the Subject Key Identifier ski.
Parameters:
Name Type Description
ski string Subject Key Identifier specific to a Crypto Suite implementation, as the unique index to represent the key
Inherited From:
Overrides:
Returns:
Promise of an instance of the Key class corresponding to the ski
Type
module:api.Key

hash()

This is an implementation of module:api.CryptoSuite#hash The opts argument is not supported.
Overrides:

importKey()

This is an implementation of module:api.CryptoSuite#importKey
Overrides:

setCryptoKeyStore(cryptoKeyStore)

Set the cryptoKeyStore. When the application needs to use a key store other than the default, it should use the Client newCryptoKeyStore to create an instance and use this function to set the instance on the CryptoSuite.
Parameters:
Name Type Description
cryptoKeyStore CryptoKeyStore The cryptoKeyStore.
Overrides:

sign()

This is an implementation of module:api.CryptoSuite#sign Signs digest using key k.
Overrides:

verify(key, signature, digest)

Verifies signature against key and digest
Parameters:
Name Type Description
key module:api.Key Signing verification key (public key)
signature Array.<byte> The signature to verify
digest Array.<byte> The digest that the signature was created for
Inherited From:
Overrides:
Returns:
true if the signature verifies successfully
Type
boolean
