Premature end of stream in PartialInputStream

[Marco Iovoli]

I'm getting a "Premature end of stream in PartialInputStream" error when I try to decrypt an encrypted file. The encrypted file does get decrypted though with the exception of the last sentence (which is when the error occurs). The stack trace is:

   at Org.BouncyCastle.Bcpg.BcpgInputStream.PartialInputStream.Read(Byte[] buffer, Int32 offset, Int32 count)

I have tried everything decryptTo, DecryptFile, etc.and always get the same error. I have set the ContentType to Text and Utf8 without any improvement. I have also tried to load in memorystream and still get same error.

The encrypted file is plain text.

Hi Marco,

Do you have by any chance test encrypted file that fails, of course with the corresponding private key?

Or eventually do you know what software was used for the encryption.

Hi Peter,

I'm trying to find out what software was used to encrypt the file. I will post as soon as I know. But I have attached the private key file (i'll regenerate a new key pair, after this is fixed) and the encrypted file causing the issue.

For your information, when I encrypt a file using the exact same public key I gave them, the decryption works fine for both encrypted ascii or binary file. Hope you can help with this.

Thanks.

Thank you for sending me the files Marco,

An updated version of the library has been released today where this error should have been fixed.

You can download the updated version from our customers' section located at http://www.didisoft.com/customers/
