speed - test library performance
SYNOPSIS
openssl speed [-engine id] [md2] [mdc2] [md5] [hmac] [sha1] [rmd160] [idea-cbc] [rc2-cbc] [rc5-cbc] [bf-cbc] [des-cbc] [des-ede3] [rc4]
[rsa512] [rsa1024] [rsa2048] [rsa4096] [dsa512] [dsa1024] [dsa2048] [idea] [rc2] [des] [rsa] [blowfish]
DESCRIPTION
This command is used to test the performance of cryptographic algorithms.
OPTIONS -engine id
specifying an engine (by it's unique id string) will cause speed to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default for all available algorithms.
[zero or more test algorithms]
If any options are given, speed tests those algorithms, otherwise all of the above are tested.

gendsa - generate a DSA private key from a set of parameters
SYNOPSIS
openssl gendsa [-out filename] [-des] [-des3] [-idea] [-rand file(s)] [-engine id] [paramfile]
DESCRIPTION
The gendsa command generates a DSA private key from a DSA parameter file (which will be typically generated by the openssl dsaparam com-
mand).
OPTIONS
-des|-des3|-idea
These options encrypt the private key with the DES, triple DES, or the IDEA ciphers respectively before outputting it. A pass phrase is
prompted for. If none of these options is specified no encryption is used.
-rand file(s)
a file or files containing random data used to seed the random number generator, or an EGD socket (see RAND_egd(3)). Multiple files
can be specified separated by a OS-dependent character. The separator is ; for MS-Windows, , for OpenVMS, and : for all others.
-engine id
specifying an engine (by it's unique id string) will cause req to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default for all available algorithms.
paramfile
This option specifies the DSA parameter file to use. The parameters in this file determine the size of the private key. DSA parameters
can be generated and examined using the openssl dsaparam command.
NOTES
DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.

Hey together,
You should know, that I'am relatively new to shell scripting, so my solution is probably a little awkward.
Here is the script:

Evening,
I am attempting to change the speed and duplex settings on a single interface on a bge card on an m3000 SPARC server. Currently the settings are as follows:

Hi all,
I have problem with searching hundreds of CSV files, the problem is that search is lasting too long (over 5min).
Csv files are "," delimited, and have 30 fields each line, but I always grep same 4 fields - so is there a way to grep just those 4 fields to speed-up search.
Example:... (11 Replies)

Hello,
I am using sed in a for loop to replace text in a 100MB file. I have about 55,000 entries to convert in a csv file with two entries per line. The following script works to search file.txt for the first field from conversion.csv and then replace it with the second field. While it works fine,... (15 Replies)
I have 1.6 GB (and growing) of files with needed data between the 11th and 34th line (inclusive) of the second column of comma delimited files. There is also a lot of stray white space in the file that needs to be trimmed. They have DOS-like end of lines.
I need to transpose the 11th through... (13 Replies)
I've got at least 30,000 XML files that I'm using the grep command to get their filename. Can I use the head command to grab just the beginning 8 lines and compare that instead of parsing the whole document? It would speed things up! or maybe grep -m? (49 Replies)
I have a BASH script that runs a continuous loop, reading a line from a file, and then spawning a background process to use it. I've placed "date" commands inside it to see where it's slowing down, and everything inside -- including reading the line from the file -- is fast, but the loop bogs... (34 Replies)
