[VB.NET]
Property MDPHashAlgorithm As TSBPDFDigestMethod

[Pascal]
property MDPHashAlgorithm : TSBPDFDigestMethod;

[C++]
TSBPDFDigestMethod get_MDPHashAlgorithm();
void set_MDPHashAlgorithm(TSBPDFDigestMethod Value);

[PHP]
integer get_MDPHashAlgorithm()
void set_MDPHashAlgorithm(integer $Value)

Values:

[.NET]	[Pascal]	[C++]	Description
dmMD5 = 1	dmMD5	dmMD5 = 0	MD5 digest
dmSHA1 = 2	dmSHA1	dmSHA1 = 1	SHA1 digest
dmUnknown = 255	dmUnknown	dmUnknown = 2	Unknown digest method

Description

Use this property to specify the hash algorithm used with MDP (certification) signature. The default value is dmMD5. Use of this property makes sense only when SignatureType is stMDP.
Please note that neither signing nor verification of MDP signatures made over the PDF document with templates is supported. If you attempt to sign or verify such document, exception is risen.
