createPBE
public static EncryptedContentInfo createPBE(PBEAlgorithm keyGenAlg, Password password, byte[] salt, int iterationCount, KeyGenerator.CharToByteConverter charToByteConverter, byte[] toBeEncrypted) throws CryptoManager.NotInitializedException, java.security.NoSuchAlgorithmException, java.security.InvalidKeyException, java.security.InvalidAlgorithmParameterException, TokenException, java.io.CharConversionException
- Creates a new EncryptedContentInfo, where the data is encrypted
with a password-based key.
- Parameters:
keyGenAlg
- The algorithm for generating a symmetric key from a password, salt, and iteration count.password
- The password to use in generating the key.salt
- The salt to use in generating the key.iterationCount
- The number of hashing iterations to perform while generating the key.charToByteConverter
- The mechanism for converting the characters in the password into bytes. If null, the default mechanism will be used, which is UTF8.toBeEncrypted
- The bytes to be encrypted and stored in the EncryptedContentInfo. Before they are encrypted, they will be padded using PKCS padding.- Throws:
CryptoManager.NotInitializedException
java.security.NoSuchAlgorithmException
java.security.InvalidKeyException
java.security.InvalidAlgorithmParameterException
TokenException
java.io.CharConversionException
decrypt
public byte[] decrypt(Password pass, KeyGenerator.CharToByteConverter charToByteConverter) throws java.lang.IllegalStateException, CryptoManager.NotInitializedException, java.security.NoSuchAlgorithmException, InvalidBERException, java.io.IOException, java.security.InvalidKeyException, java.security.InvalidAlgorithmParameterException, TokenException, IllegalBlockSizeException, BadPaddingException
- Decrypts the content of an EncryptedContentInfo encrypted with a
PBE key.
- Parameters:
pass
- The password to use in generating the PBE decryption key.charToByteConverter
- The converter for converting the password characters into bytes. May be null to use the default.- Returns:
- The decrypted contents of the EncryptedContentInfo. The contents are first unpadded using the PKCS padding mechanism.
- Throws:
java.lang.IllegalStateException
CryptoManager.NotInitializedException
java.security.NoSuchAlgorithmException
InvalidBERException
java.io.IOException
java.security.InvalidKeyException
java.security.InvalidAlgorithmParameterException
TokenException
IllegalBlockSizeException
BadPaddingException
