Ways to generate symmetric and asymmetric keys. Ask Question. Do you suggest any other method to generate more secure asymmetric keys? Encryption openssl rsa random asymmetric. Is is only time taken for encryption and decryption? Yes, it is: larger key require more computational power to encrypt and decrypt. The idea behind this. 
This is part 3 of using Public Key Infrastructure (PKI) and Private Key Cryptography for your Windows Server 2012 environment. Part 1: Selecting a Key Size for Your Root Certificate Server in Windows Server 2012 AD CS. Part 2: Selecting a Cryptographic Key Provider in Windows Server 2012 AD CS. In this post, we’ll look at the time involved to generate asymmetric key pars.

- Primary Key Generation Using Oracle's Sequence. Oracle provides the sequence utility to automatically generate unique primary keys. To use this utility to auto-generate primary keys for a CMP entity bean, you must create a sequence table and use the @AutomaticKeyGeneration annotation to point to this table.
- Hello Tom, I have a question on using GUIDs as primary keys. Our application is being developed on 11gR2 with a 3-node RAC. The development team has introduced a new column to almost all of the tables which is technically a UUID generated by the application code.
- Hi All Is there a way that I can get access to self generate a random number for a primary key, which obviously has to be unique each time. Kindest Regards Peter [email protected] - Do you Yahoo!? SiteBuilder - Free, easy-to-use web site design software.
Public key private key generator. One version gets a random number greater than or equal to 0 and less than 1, with 38 digits to the right of the decimal point (38-digit precision). The other version gets a random Oracle Database number x, where x is greater than or equal to a specified lower limit and less than a.

1 do {
2 $random = generate_random_primary_key();
3 mysql_query(check if $random exists in database);
4 if not { insert data row to MySQL, quit loop } // else continue with loop
5 } while $random is in database
However, I have a couple of concerns:
1. Wouldn't this be a little slow and database-intensive, especially when the database already contains a lot of entries as I'll be checking the primary key's existence every time I need to insert an entry? And worse, it'll be inside a loop that continues until a non-existing primary key is found (imagine a 'nearly full' database).
2. I'm concerned about multiple users doing inserts at the same time. How can I be sure that there won't be another user inserting another entry using the same 'random' primary key in between lines 3 and 4?
Any comments would be very much be welcomed!
