why is scanf skipping large part of input from file redirect? [C]

Asked 2022-Feb-08 at 21:19

I have this program called simplechain.c here which basically has a program fork itself once, the child does the same and that keeps going a certain amount of times, then each process now (in reverse order due to a wait()) reads some amount of characters and prints them once they have enough:

The short answer is Buffered I/O.

The programs all share the same file stream. Reading from a file, the first process to read the file gets a block of data (probably 512 or 4096 bytes) which the others don't see, but the file read position for the others moves. Rinse and repeat. If you used file descriptor I/O, you wouldn't get the same buffering effect. If you read some data using file streams before you did the forking, you'd get another set of results (all showing the same data). If the input was not a file but a pipe or something else, you'd get other results again.

You could probably fix it by setting the buffer size small, or unbuffered:

Asked 2020-Dec-17 at 22:48

We have built a Java Web service client project using Axis in order to connect and call a Web Service. Our Java client is deployed in JBOSS 4 that is using Java JDK 1.5.

We are facing an issue with the SSLHandshake: Prime size must be multiple of 64, and can only range from 512 to 1024 (inclusive) (below is the exception).

You can use a reverse proxy to allow clients to connect the reverse proxy using https while internally exposing the service over http.

Obviously you should be sure that your network configuration won't allow any external connections directly to your app server, as if clients started connecting via http their credentials would be vulnerable.

This approach will not mitigate any other security issues with the JDK and libraries you are using, e.g. if you were using a version of ognl with vulnerabilities.

Here's documentation on using nginx as a reverse proxy: https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/?_ga=2.104366976.1869010128.1608244655-193116785.1608244655

QUESTION

Can't figure out why my PDF signature is not LTV enabled

Asked 2020-Mar-05 at 14:45

I'm generating a PDF document with signature and I want it to be LTV enabled. For this, I sign the PDF when creating it and then I add the second version containing the DSS with the validation related informations (VRI). As I found in some articles, I need to add the Certificate chain (without the root certificate - Authority) and the Certificate Revocation List (CRL). In my case, both will have 2 elements. After that I add the entry for the VRI which is a SHA-1 hash of the signature content (found in the first PDF verion in the /Contents ) with the value which refers the Certificates and CRL mentioned above.

For both the certificates and the revocation list elements I use the raw bytes stream of the content.

Here is my PDF sample

Edit

The way I obtain the CRL information is uising WynCrypt like this:

Just had a quick look and objects 15 and 16 are OCSP responses but you are adding them as CRLs:

Stream Object 16

This ASN.1 Decoder is very handy!
