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.
