Method Details

setKeySize

public void setKeySize(int keyBits)

Description copied from class: EncryptionHeader

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

Overrides:

setKeySize in class EncryptionHeader

copy

public CryptoAPIEncryptionHeader copy()

Specified by:

copy in interface org.apache.poi.common.Duplicatable

Overrides:

copy in class StandardEncryptionHeader
