The following example creates a named key container and adds a signature key pair and an exchange key pair to the container. This example can be run without problem even if the named key container and cryptographic keys already exist.

Generation of Public and Private key in RSA. The flowcharts above shows how to generate a public and private key using RSA. Button with the following code. Algorithms for generating RSA keys. We need two primary algorithms for generating RSA keys using Python − Cryptomath module and Rabin Miller module. Cryptomath Module. The source code of cryptomath module which follows all the basic implementation of RSA algorithm is as follows −.

An application should not use the default key container to store private keys. When multiple applications use the same container, one application may change or destroy the keys that another application needs to have available. It is recommended that applications use key containers that are linked to the application. Doing so reduces the risk of other applications tampering with keys that are necessary for an application to function properly.

This example demonstrates the following tasks and CryptoAPI functions:

1. It attempts to acquire the named key container. If the named key container does not already exist, it is created.
2. If a signature key pair does not exist in the key container, it creates a signature key pair within the key container.
3. If an exchange key pair does not exist in the key container, it creates an exchange key pair within the key container.

These operations only need to be performed once for each user on each computer. If the named key container and key pairs have already been created, this sample performs no operations.

This example uses the following CryptoAPI functions:

This example uses the function MyHandleError. The code for this function is included with the sample. Code for this and other auxiliary functions is also listed under General Purpose Functions.

Generating RSA keys

The following steps are involved in generating RSA keys −

• Create two large prime numbers namely p and q. The product of these numbers will be called n, where n= p*q

• Generate a random number which is relatively prime with (p-1) and (q-1). Let the number be called as e.

• Calculate the modular inverse of e. The calculated inverse will be called as d.

If the license in the backup is a permanent license and is still valid, the new tenant will get a temporary license key valid for 90 days and need a new permanent license key. If the license in the backup is a temporary license key or an expired license, this license will be deleted from the new tenant and it is immediately in lock down.

In S4HANA there are no developer keys and object keys any more. Background of this change be SAP can be found in OSS note: 2309060 – The SSCR license key procedure is not supported in SAP S/4 HANA. So in S4HANA, you must set up authorizations for SDEVELOP properly.
