Function crypt4gh::header::reencrypt

pub fn reencrypt(
    header_packets: Vec<Vec<u8>>, 
    keys: &[Keys], 
    recipient_keys: &HashSet<Keys>, 
    trim: bool
) -> Result<Vec<Vec<u8>>, Crypt4GHError>

Reencrypts the header.

Decrypts the header using the keys and then, encrypts the content again for every key in recipient_keys. If trim is specified, the packets that cannot be decrypted are discarded.
