Method Detail

getChainingMode

public ChainingMode getChainingMode()

setChainingMode

protected void setChainingMode(ChainingMode chainingMode)

getFlags

public int getFlags()

setFlags

public void setFlags(int flags)

getSizeExtra

public int getSizeExtra()

setSizeExtra

public void setSizeExtra(int sizeExtra)

getCipherAlgorithm

public CipherAlgorithm getCipherAlgorithm()

setCipherAlgorithm

public void setCipherAlgorithm(CipherAlgorithm cipherAlgorithm)

getHashAlgorithm

public HashAlgorithm getHashAlgorithm()

setHashAlgorithm

public void setHashAlgorithm(HashAlgorithm hashAlgorithm)

getKeySize

public int getKeySize()

setKeySize

public void setKeySize(int keyBits)

Sets the keySize (in bits). Before calling this method, make sure to set the cipherAlgorithm, as the amount of keyBits gets validated against the list of allowed keyBits of the corresponding cipherAlgorithm

getBlockSize

public int getBlockSize()

setBlockSize

public void setBlockSize(int blockSize)

getKeySalt

public byte[] getKeySalt()

setKeySalt

public void setKeySalt(byte[] salt)

getCipherProvider

public CipherProvider getCipherProvider()

setCipherProvider

public void setCipherProvider(CipherProvider providerType)

getCspName

public java.lang.String getCspName()

setCspName

public void setCspName(java.lang.String cspName)

copy

public abstract EncryptionHeader copy()

Specified by:

copy in interface Duplicatable

Returns:

a deep copy of the implementing class / instance

getGenericProperties

public java.util.Map<java.lang.String,java.util.function.Supplier<?>> getGenericProperties()

Specified by:

getGenericProperties in interface GenericRecord
