Constructor Detail

GcmNoPadding

public GcmNoPadding()

The constructor; creates a new instance of the AES/GCM/NoPadding symmetric cipher algorithm.

Applications should never use this constructor, instead the symmetric cipher algorithm should be requested from the appropriate JCA/JCE cryptographic service provider as follows: Cipher.getInstance("AES/GCM/NoPadding", "Entrust").

FIPS 140-2:

FIPS Service: Modify Object

This API is part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; use of this API causes the caller to assume the FIPS 140-2 user role and accesses the following FIPS 140-2 logical interfaces:

• control input interface (API call)
• status output interface (exceptions)

Since:

8.0

Method Detail

engineSetMode

protected final void engineSetMode(java.lang.String mode)
                            throws java.security.NoSuchAlgorithmException

Description copied from class: SymmetricBlockCipher

Sets the block mode of this cipher.

FIPS 140-2:

FIPS Service: Modify Object

This API is part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; use of this API causes the caller to assume the FIPS 140-2 user role and accesses the following FIPS 140-2 logical interfaces:

• control input interface (API call, parameters)
• status output interface (exceptions)

Overrides:

engineSetMode in class SymmetricBlockCipher

Parameters:

mode - [FIPS 140-2 control input] the cipher block mode

Throws:

java.security.NoSuchAlgorithmException - [FIPS 140-2 status output] if the requested cipher block mode is not supported

engineSetPadding

protected void engineSetPadding(java.lang.String padding)
                         throws javax.crypto.NoSuchPaddingException

Description copied from class: SymmetricBlockCipher

Sets the padding type of this cipher.

FIPS 140-2:

FIPS Service: Modify Object

This API is part of the logical interface to the Toolkit's FIPS 140-2 cryptographic module; use of this API causes the caller to assume the FIPS 140-2 user role and accesses the following FIPS 140-2 logical interfaces:

• control input interface (API call, parameters)
• status output interface (exceptions)

Overrides:

engineSetPadding in class SymmetricBlockCipher

Parameters:

padding - [FIPS 140-2 control input] the padding type

Throws:

javax.crypto.NoSuchPaddingException - [FIPS 140-2 status output] if the requested padding type does not exist
