EVP_PKEY_CTX_new(3SSL) OpenSSL EVP_PKEY_CTX_new(3SSL)NAME
EVP_PKEY_CTX_new, EVP_PKEY_CTX_new_id, EVP_PKEY_CTX_dup, EVP_PKEY_CTX_free - public key algorithm context functions.
SYNOPSIS
#include <openssl/evp.h>
EVP_PKEY_CTX *EVP_PKEY_CTX_new(EVP_PKEY *pkey, ENGINE *e);
EVP_PKEY_CTX *EVP_PKEY_CTX_new_id(int id, ENGINE *e);
EVP_PKEY_CTX *EVP_PKEY_CTX_dup(EVP_PKEY_CTX *ctx);
void EVP_PKEY_CTX_free(EVP_PKEY_CTX *ctx);
DESCRIPTION
The EVP_PKEY_CTX_new() function allocates public key algorithm context using the algorithm specified in pkey and ENGINE e.
The EVP_PKEY_CTX_new_id() function allocates public key algorithm context using the algorithm specified by id and ENGINE e. It is normally
used when no EVP_PKEY structure is associated with the operations, for example during parameter generation of key genration for some
algorithms.
EVP_PKEY_CTX_dup() duplicates the context ctx.
EVP_PKEY_CTX_free() frees up the context ctx.
NOTES
The EVP_PKEY_CTX structure is an opaque public key algorithm context used by the OpenSSL high level public key API. Contexts MUST NOT be
shared between threads: that is it is not permissible to use the same context simultaneously in two threads.
RETURN VALUES
EVP_PKEY_CTX_new(), EVP_PKEY_CTX_new_id(), EVP_PKEY_CTX_dup() returns either the newly allocated EVP_PKEY_CTX structure of NULL if an error
occurred.
EVP_PKEY_CTX_free() does not return a value.
SEE ALSO EVP_PKEY_new(3)HISTORY
These functions were first added to OpenSSL 1.0.0.

Introduction
I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin
-r-xr-xr-x 1 bin bin ... (6 Replies)
I have a file which looks roughly like this:
996 mmmmmmm
996 xxxxxxxxxxxxx
99600 ssssssssss
9964 fffffffffffff
and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.
I've got the Oracle installation guide for it and I got as far as:

I don't have a CD-ROM by that name and a web search for that... (21 Replies)
Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)
Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries. Now I had found a closed reference to adding time titled "add up time with xx:yy format in bash how?" In it, the example works great for that formatted list of times... This is the reply code...

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
