Re: [iText-questions] Problem with iTextSharp
This is because the ';'is a predefined special character for XMP metadata as defined in ISO 16682-1. There are no issues with iText.

Re: [iText-questions] Problem with ITextSharp PKSC7 Signing
Paulo, Thank you for taking the time to respond to this issue. Please see my previous post which shows what I am doing. It is very strange that PKCS1 signatures verifies and PKCS7 does not with .NET. If I use BC crypto the reverse is true. http://www.nabble.com/pkcs1-to-pkcs7-external-signatures---to13803022.html#a13803022 I can also send you sample signed pfds if you wish. Thanks in advance for your help.

Re: [iText-questions] Problem with ITextSharp PKSC7 Signing
BC code to get PKCS1 signature bytes using certificate with exported private
key (pfxFilePath):
string alias = null;
Pkcs12Store pk12 = new Pkcs12Store(new
FileStream(pfxFilePath, FileMode.Open, FileAccess.Read),
password.ToCharArray());
IEnumerator en = pk12.Aliases.GetEnumerator();
while (en.MoveNext())
{
alias = ((string)en.Current);
if (pk12.IsKeyEntry(alias))
break;
}
AsymmetricKeyParameter akp = pk12.GetKey(alias).Key;
Org.BouncyCastle.Crypto.Digests.Sha1Digest dig = new
Org.BouncyCastle.Crypto.Digests.Sha1Digest();
Org.BouncyCastle.Crypto.Signers.RsaDigestSigner sig = new
Org.BouncyCastle.Crypto.Signers.RsaDigestSigner(dig);
sig.Init(true, akp);
sig.BlockUpdate(hashToSign, 0, hashToSign.Length);
byte[] extSig = sig.GenerateSignature();
.NET code I use RSACryptoServiceProvider with SHA1 and call SignHash() to
get the PKCS1 signature.
I then use iText's PdfPKS7 class to get the encoded signatures ( 1 or 7 ).
PKCS1 verifies and PKCS7 does not.
