Examples of codec.pkcs7.SignedAndEnvelopedData

codec.pkcs7.Data
The definition of this structure is:
```
 SignedAndEnvelopedData ::= SEQUENCE { version Version, recipientInfos RecipientInfos, digestAlgorithms DigestAlgorithmIdentifiers, encryptedContentInfo EncryptedContentInfo, certificates [0] IMPLICIT ExtendedCertificatesAndCertificates OPTIONAL, crls [1] IMPLICIT CertificateRevocationLists OPTIONAL, signerInfos SignerInfos } DigestAlgorithmIdentifiers ::= SET OF DigestAlgorithmIdentifier SignerInfos ::= SET OF SignerInfo 
```
Please note that SignerInfo structures only store the issuer and serial number of the signing certificate but not the certificate itself. Neither are certificates added automatically by this class when signing is done. If a certificate shall be included with an instance of this class then it must be added explicitly by calling addCertificate(..).
The encryption and decryption methods of this class do not work like update(...) of a Cipher class but encrypt and decrypt data with a freshly initialized cipher instance. @author Volker Roth @author Markus Tak @version "$Id: SignedAndEnvelopedData.java,v 1.6 2002/08/28 21:40:35 jpetersExp $"
