Method Detail

engineGetParameterback to summary
protected Object engineGetParameter(String param) throws InvalidParameterException

Implements abstract java.security.SignatureSpi.engineGetParameter.

Doc from java.security.SignatureSpi.engineGetParameter.

Gets the value of the specified algorithm parameter. This method supplies a general-purpose mechanism through which it is possible to get the various parameters of this object. A parameter may be any settable parameter for the algorithm, such as a parameter size, or a source of random bits for signature generation (if appropriate), or an indication of whether to perform a specific but optional computation. A uniform algorithm-specific naming scheme for each parameter is desirable but left unspecified at this time.

Parameters
param:String

the string name of the parameter.

Returns:Object

the object that represents the parameter value, or null if there is none.

Annotations
@Override
@SuppressWarnings:deprecation
Exceptions
InvalidParameterException:
if param is an invalid parameter for this engine, or another exception occurs while trying to get this parameter.
engineInitSignback to summary
protected void engineInitSign(PrivateKey privateKey) throws InvalidKeyException

Implements abstract java.security.SignatureSpi.engineInitSign.

Doc from java.security.SignatureSpi.engineInitSign.

Initializes this Signature object with the specified private key for signing operations.

Parameters
privateKey:PrivateKey

the private key of the identity whose signature will be generated.

Annotations
@Override
Exceptions
InvalidKeyException:
if the key is improperly encoded, parameters are missing, and so on.
engineInitVerifyback to summary
protected void engineInitVerify(PublicKey publicKey) throws InvalidKeyException

Implements abstract java.security.SignatureSpi.engineInitVerify.

Doc from java.security.SignatureSpi.engineInitVerify.

Initializes this Signature object with the specified public key for verification operations.

Parameters
publicKey:PublicKey

the public key of the identity whose signature is going to be verified.

Annotations
@Override
Exceptions
InvalidKeyException:
if the key is improperly encoded, parameters are missing, and so on.
engineSetParameterback to summary
protected void engineSetParameter(String param, Object value) throws InvalidParameterException

Implements abstract java.security.SignatureSpi.engineSetParameter.

Doc from java.security.SignatureSpi.engineSetParameter.

Sets the specified algorithm parameter to the specified value. This method supplies a general-purpose mechanism through which it is possible to set the various parameters of this object. A parameter may be any settable parameter for the algorithm, such as a parameter size, or a source of random bits for signature generation (if appropriate), or an indication of whether to perform a specific but optional computation. A uniform algorithm-specific naming scheme for each parameter is desirable but left unspecified at this time.

Parameters
param:String

the string identifier of the parameter.

value:Object

the parameter value.

Annotations
@Override
@SuppressWarnings:deprecation
Exceptions
InvalidParameterException:
if param is an invalid parameter for this Signature object, the parameter is already set and cannot be set again, a security exception occurs, and so on.
engineSignback to summary
protected byte[] engineSign() throws SignatureException

Implements abstract java.security.SignatureSpi.engineSign.

Doc from java.security.SignatureSpi.engineSign.

Returns the signature bytes of all the data updated so far. The format of the signature depends on the underlying signature scheme.

Returns:byte[]

the signature bytes of the signing operation's result.

Annotations
@Override
Exceptions
SignatureException:
if the engine is not initialized properly or if this signature algorithm is unable to process the input data provided.
engineUpdateback to summary
protected void engineUpdate(byte input)

Implements abstract java.security.SignatureSpi.engineUpdate.

Doc from java.security.SignatureSpi.engineUpdate.

Updates the data to be signed or verified using the specified byte.

Parameters
input:byte

the byte to use for the update.

Annotations

engineUpdateback to summary
protected void engineUpdate(byte[] input, int offset, int len)

Implements abstract java.security.SignatureSpi.engineUpdate.

Doc from java.security.SignatureSpi.engineUpdate.

Updates the data to be signed or verified, using the specified array of bytes, starting at the specified offset.

Parameters
input:byte[]

the array of bytes

offset:int

the offset to start from in the array of bytes

len:int

the number of bytes to use, starting at offset

Annotations
@Override
engineVerifyback to summary
protected boolean engineVerify(byte[] sigBytes) throws SignatureException

Implements abstract java.security.SignatureSpi.engineVerify.

Doc from java.security.SignatureSpi.engineVerify.

Verifies the passed-in signature.

Parameters
sigBytes:byte[]

the signature bytes to be verified.

Returns:boolean

true if the signature was verified, false if not.

Annotations
@Override
Exceptions
SignatureException:
if the engine is not initialized properly, the passed-in signature is improperly encoded or of the wrong type, if this signature algorithm is unable to process the input data provided, etc.
