Generating SSL key in Mac

This info I found from


I’d like to use my Mac OS X with https for local development tests. How can I easily make Apache2 respond to ssl, just for test proposes – I don’t want a real certificate, just a fake to make local https work ?


Generating the private key:

openssl genrsa -des3 -out server.key 1024


Generating RSA private key, 1024 bit long modulus …………………………………………………++++++ ……..++++++ e is 65537 (0x10001) Enter PEM pass phrase: Verifying password – Enter PEM pass phrase:

enter a passphrase for your private key.
Generating the CSR (certificate signing request):

openssl req -new -key server.key -out server.csr

It will request details like this:

Country Name (2 letter code) [GB]:
State or Province Name (full name) [Berkshire]:
Locality Name (eg, city) [Newbury]:
Organization Name (eg, company) [My Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your server’s hostname) []:
Email Address []:
Please enter the following ‘extra’ attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

it’s fairly straightforward, the common name is your server’s hostname as it says in brackets.

Generating the self signed certificate:

openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Configuring SSL in httpd.conf for Apache:

SSLEngine on
SSLCertificateFile /path/to/generated/server.crt
SSLCertificateKeyFile /path/to/generated/server.key

(replace path appropriately with the path to your certificate and key)

Restart Apache:

apachectl restart

Apache will ask you for the passphrase to your key. If you think you will be shutting the server down a lot, you may want to remove the passphrase from the key so you can avoid entering it each time. If not, don’t worry about it. If so, complete this step after step 2 (Generating the CSR):

cp server.key server.key.copy
openssl rsa -in server.key.copy -out server.key

Seperate certain data in file to another file.

Let say, i have many raw files, example data files generated from system. Every day the system generates the raw files, with pipe | seperated. At the end of the month i want to extract certain data from each of the files. Another problem arise is, these files contains more 100K of lines.

List of files in my unix server

Content of the file

Extract aby from all the listed files. Manually i can do each files like this
more mixed_raw_data_20080101.csv | grep ‘|aby’ > mixed_raw_data_20080101.csv.extract

But what if i have to extract for the whole month which has 30 files….

for f in mixed_raw_data_*.csv; do more $f | grep ‘|aby’ > $f.extract ; done;
