Creates a new EncryptedPrivateKeyInfo, 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.
pki - The PrivateKeyInfo 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
