Constructor & Destructor Documentation

LtvVerification()

iText.Signatures.LtvVerification.LtvVerification ( PdfDocument  document )

inline

The verification constructor.

The verification constructor. This class should only be created with PdfStamper.getLtvVerification() otherwise the information will not be added to the Pdf.

Parameters

document

The iText.Kernel.Pdf.PdfDocument to apply the validation to.

Member Function Documentation

AddVerification() [1/2]

virtual bool iText.Signatures.LtvVerification.AddVerification ( String  signatureName, ICollection< byte[]>  ocsps, ICollection< byte[]>  crls, ICollection< byte[]>  certs  )

inlinevirtual

Adds verification to the signature.

Parameters

signatureName	name of the signature
ocsps	collection of DER-encoded BasicOCSPResponses
crls	collection of DER-encoded CRLs
certs	collection of DER-encoded certificates

Returns

boolean

AddVerification() [2/2]

virtual bool iText.Signatures.LtvVerification.AddVerification ( String  signatureName, IOcspClient  ocsp, ICrlClient  crl, LtvVerification.CertificateOption  certOption, LtvVerification.Level  level, LtvVerification.CertificateInclusion  certInclude  )

inlinevirtual

Add verification for a particular signature.

Parameters

signatureName	the signature to validate (it may be a timestamp)
ocsp	the interface to get the OCSP
crl	the interface to get the CRL
certOption	options as to how many certificates to include
level	the validation options to include
certInclude	certificate inclusion options

Returns

true if a validation was generated, false otherwise

ConvertToHex()

static String iText.Signatures.LtvVerification.ConvertToHex ( byte[]  bytes )

inlinestatic

Converts an array of bytes to a String of hexadecimal values

Parameters

bytes

a byte array

Returns

the same bytes expressed as hexadecimal values

Merge()

virtual void iText.Signatures.LtvVerification.Merge ( )

inlinevirtual

Merges the validation with any validation already in the document or creates a new one.
