Hello,
I am trying to migrate my old digital signature program to the new
iText-5.3.0, but it failed.
I tried to test the digital signature in the iText-5.3.0 tutorial but
it not worked with Smartcard. It gots some exception:
java.security.NoSuchAlgorithmException: no such algorithm: SHA1
for provider SunPKCS11-GD
This is NOT an iText issue.
The error message explains why: you are trying to create a message
digest (SHA1, an algorithm that is no longer recommended as you could
read in the white paper) using the security provider SunPKCS11-GD which
doesn't support the algorithm of your choice.
The solution is: use another security provider to create the hash.
