Hashing is a one way function (well, a mapping). It’s irreversible, you apply the secure hash algorithm and you cannot get the original string back. The most you can do is to generate what’s called “a collision”, that is, finding a different string that provides the same hash. Cryptographically secure hash algorithms are designed to … Read more
SQLite has hooks built-in for encryption which are not used in the normal distribution, but here are a few implementations I know of: SEE – The official implementation. wxSQLite – A wxWidgets style C++ wrapper that also implements SQLite’s encryption. SQLCipher – Uses openSSL’s libcrypto to implement. SQLiteCrypt – Custom implementation, modified API. botansqlite3 – … Read more
I had the same issue after copying my key pair from one machine to another. The solution for me was the set the trust level of the keys: gpg –edit-key <KEY_ID> gpg> trust You will be asked to select the trust level from the following: 1 = I don’t know or won’t say 2 = … Read more
You can’t just change the delimiters from —- BEGIN SSH2 PUBLIC KEY —- to —–BEGIN RSA PUBLIC KEY—– and expect that it will be sufficient to convert from one format to another (which is what you’ve done in your example). This article has a good explanation about both formats. What you get in an RSA … Read more
Base64 is not encryption — it’s an encoding. It’s a way of representing binary data using only printable (text) characters. See this paragraph from the wikipedia page for HTTP Basic Authentication: While encoding the user name and password with the Base64 algorithm typically makes them unreadable by the naked eye, they are as easily decoded … Read more
Encoding transforms data into another format using a scheme that is publicly available so that it can easily be reversed. Encryption transforms data into another format in such a way that only specific individual(s) can reverse the transformation. For Summary – Encoding is for maintaining data usability and uses schemes that are publicly available. Encryption … Read more
Personally, I would use mcrypt like others posted. But there is much more to note… How do I encrypt and decrypt a password in PHP? See below for a strong class that takes care of everything for you: What is the safest algorithm to encrypt the passwords with? safest? any of them. The safest method … Read more
Python has no built-in encryption schemes, no. You also should take encrypted data storage serious; trivial encryption schemes that one developer understands to be insecure and a toy scheme may well be mistaken for a secure scheme by a less experienced developer. If you encrypt, encrypt properly. You don’t need to do much work to … Read more
I found a way that seems to work better for me: ssh-keygen -y -f <private key file> That command will output the public key for the given private key, so then just compare the output to each *.pub file.
This is the first page that shows up via Google and the security vulnerabilities in all the implementations make me cringe so I’m posting this to add information regarding encryption for others as it has been 7 Years from the original post. I hold a Masters Degree in Computer Engineering and spent a lot of … Read more
