The EVP functions support the ability to generate parameters and keys if required for EVP_PKEY objects. Since these functions use random numbers you should ensure that the random number generator is appropriately seeded as discussed here.

Parameter Generation[edit]

Parameter generation is supported for the following EVP_PKEY types only:

Basically my idea was to, upon visiting each vertex using the BFS assign its children to its own depth + 1 or some method like that. I'd like to add lock & key puzzle generation to this dungeon, ala metazelda My approach differs somewhat from the authors, especially when it comes to generating a dungeon.Since I don't build a graph of my rooms initially like is done in metazelda (where child and parent rooms are linked to each other via edges) - I need to do this after my dungeon layout is already established. So the breadth first search method did help then? From my understanding this should be possible using the delaunay triangulation algorithm.I've gone ahead and calculated the delaunay triangulation algorithm and visualized it - but how do I turn this data into a graph?I have essentially a list of input vertices (the coordinates of the center tile of each room), and then a list of triangles generated via the algorithm.How can I turn this data into a graph of interconnected nodes, representing the parent / child relationships of my rooms?Thanks!. Hello, thanks for reading / any help you can offer.I have an algorithm that is generating a dungeon with rooms of various sizes that are connected by hallways. Procedural dungeon generation node graph lock and key west.

  • Table of Contents This a snippet to generate a psuedo random password fast via the command line with OpenSSL. It generates a number of random bytes, which can either be output raw, as Base64 or as HEX. The Base64 output is a good password most of the time.
  • OpenSSL is great library and tool set used in security related work. While talking security we can not deny that passwords and random numbers are important subjects. In this tutorial we will learn how to generate random numbers and passwords with OpenSSL. Generate Base64 Random Numbers.
  • Nov 14, 2019  10 Ways to Generate a Random Password from the Linux Command Line Lowell Heddings @lowellheddings Updated November 14, 2019, 2:44pm EDT One of the great things about Linux is that you can do the same thing hundreds of different ways—even something as simple as generating a random password can be accomplished with dozens of different commands.
  • A PRNG does not create randomness, it expands some initial randomness (the 'seed', here the AES key) into a long stream of pseudorandom bytes. This PRNG relies on your never reusing a counter value. So you have to make sure that the counter is always increased and cannot be forced to 'rewind'.
  • An AES key, and an IV for symmetric encryption, are just bunchs of random bytes. So any cryptographically strong random number generator will do the trick. OpenSSL provides such a random number generator (which itself feeds on whatever the operating system provides, e.g.
  • For example, I have a secret key for AES on my server and a counter in my database. Each time I want to generate a random number I increment the counter then encrypt it with AES using the secret key on my server then transform the resulting bits into the right number. Wouldn't this produce secure random number as long as my secret key is not found?
  • EVP_PKEY_EC (for ECDSA and ECDH keys)

The following sample code shows an example of how to generate parameters for each of these key types:

Key Generation[edit]

The following sample code shows an example of how to generate keys with the exception of EVP_PKEY_HMAC and EVP_PKEY_CMAC keys:

CMAC keys are generated in a simlar fashion (see EVP_Signing_and_Verifying for information on generating MAC codes):

HMAC keys can be generated in the same way as for CMAC keys but do not take a cipher. A convenience function which wraps this process exists to simplify HMAC key generation:
