With my T7300 2.0GHz and Kingston V100 64gb SSD the results are Bitlocker off → on Sequential read 243 MB/s → 140 MB/s Sequential write 74.5 MB/s → 51 MB/s Random read 176 MB/s → 100 MB/s Random write, and the 4KB speeds are almost identical. Clearly the processor is the bottleneck in this case. … Read more
Most of these answers are a bit misguided and demonstrate a confusion between salts and cryptographic keys. The purpose of including salts is to modify the function used to hash each user’s password so that each stored password hash will have to be attacked individually. The only security requirement is that they are unique per … Read more
You can use any commonly available hash algorithm (eg. SHA-1), which will give you a slightly longer result than what you need. Simply truncate the result to the desired length, which may be good enough. For example, in Python: >>> import hashlib >>> hash = hashlib.sha1(“my message”.encode(“UTF-8”)).hexdigest() >>> hash ‘104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb’ >>> hash[:10] ‘104ab42f11’
GnuPG does multi-key encryption in standard. The following command will encrypt doc.txt using the public key for Alice and the public key for Bob. Alice can decrypt using her private key. Bob can also decrypt using his private key. gpg –encrypt –recipient alice@example.com \ –recipient bob@example.com doc.txt This feature is detailed in the user guide … 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
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
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.
