/**
 * A content time-stamp allows a time-stamp token of the data to be signed to be incorporated into the signed information.
 * It provides proof of the existence of the data before the signature was created.
 * <p/>/*from   w  w  w . j  a v a 2  s  .c  om*/
 * A content time-stamp attribute is the time-stamp token of the signed data content before it is signed.
 * This attribute is a signed attribute.
 * Its object identifier is :
 * id-aa-ets-contentTimestamp OBJECT IDENTIFIER ::= { iso(1) member-body(2) us(840) rsadsi(113549) pkcs(1) pkcs-9(9) smime(16) id-aa(2) 20}
 * <p/>
 * Content time-stamp attribute values have ASN.1 type ContentTimestamp:
 * ContentTimestamp ::= TimeStampToken
 * <p/>
 * The value of messageImprint of TimeStampToken (as described in RFC 3161) is the hash of the message digest as defined in
 * ETSI standard 101733 v.2.2.1, clause 5.6.1.
 * <p/>
 * NOTE: content-time-stamp indicates that the signed information was formed before the date included in the content-time-stamp.
 * NOTE (bis): There is a small difference in treatment between the content-time-stamp and the archive-timestamp (ATSv2) when the signature
 * is attached. In that case, the content-time-stamp is computed on the raw data (without ASN.1 tag and length) whereas the archive-timestamp
 * is computed on data as read.
 *
 * @param parameters
 * @param signedAttributes
 * @return
