Migrating GPG master keys as subkeys to new master key



Currently I have 3 private GPG pairs which are all master keys. I want to convert these keys into subkeys for a new key pair (and keep that in the vault).I have read the following thread http://atom.smasher.org/gpg/gpg-migrate.txt which involes some sort of hacking the binary file to convert one master key into a subkey and replace it with another. Is it possible to combine my different keys into a new single key pair so they still remain valid, and I can refer people to signing my master k

Migrating server, don't wanna lose MySQL data. Is Master-Master setup viable?
Information Security

I am moving to a new server and thinking about how to keep my 2 MySQL server data consistent is causing me to lose both sleep and hair.
I was thinking about using a Master-Master setup to ensure that I lose nothing in the process. How viable is that. Any potential gotchas?

Amazon RDS (MySQL) -> local dev / testing server Master-Master or Master-Slave + Example?
Information Security

I'm needing to replicate data from a primary Amazon RDS MySQL database to another local server that acts as backup and a dev testing db, but I'm not sure which approach to take. I know that there are advantages and disadvantages of running Master-Master and Master-Slave, but I'm not sure of all of the pros and cons.


I was hoping that someone could enumerate these as well as to actually offer an example of setting up the recommended scenario appropriately in terms of config files and the what ports need to communicate (I'm guessing 3306 will have to be forwarded), etc.


So as noted below, since an actual Amazon RDS to remote replication isn't an o

Does altering SQL Server 2008 R2 Database Master Key seamlessly change dependent keys?
Information Security

In SQL Server 2008 R2, If I alter the database master key do I have to make any changes to certificates that change user data base encryption keys. I have an annual update requirement.


So if I do this:


USE [Master];
ALTER MASTER KEY REGENERATE WITH ENCRYPTION BY PASSWORD = 'blah((blah&something';
GO

will it also update keys encrypting all the the certificates that were created for user database encryption keys?


is there a data loss risk?


There are a lot of examples on how to make the change but I'm having trouble finding on point commentary on this speci

Is an OFFLINE Master GPG key penny-wise and pound-foolish? [closed]
Information Security
According to Debian, Alice's OFFLINE Master GPG key is used to perform only three actions:Revoke subkeys and primary keysCreate new subkeysIssue trust to other keysThus, an OFFLINE Master GPG key attempts to make it more difficult for an adversary to perform the above three actions using Alice's keys (e.g., costing 15 units of work) without changing the difficulty of gaining Alice's ONline Secret Encryption Key and Passphrase (e.g., costing 10 units of work).For which adversaries, and
