What is the simplest way of doing two way encryption in common PHP installs? I need to be able to encrypt data with a string key, and use the same key to decrypt on the other end. The security isn’t as big of a concern as the portability of the code, so I’d like to … Read more
SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do. However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that’s pretty much the only way. So to … Read more
Use a random number generator designed for cryptography. Then base-64 encode the number. This is a C# example:
I was trying to update libc in our Ubuntu server but it failed and now when I reboot the server I get a error message: Kernel panic – not syncing – Attempted to kill init! and it just hangs. What is the solution to this problem? The server is used by 10 people so I … Read more
Windows uses .cer extension for an X.509 certificate. These can be in “binary” (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer’s public key… which is, in … Read more
Update: Although this answer has been accepted a few years ago, note that its approach is now recommended against by the Apache documentation. Use a Redirect instead. See this answer.
This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through. It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again): Needless to say … Read more

jww is right — you’re referencing the wrong intermediate certificate. As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt
