Share point integration

I asked Google for some help and got this as the first link: https://learn.microsoft.com/en-us/sharepoint/dev/sp-add-ins/complete-basic-operations-using-sharepoint-rest-endpoints

How to set up connection with Sharepoint

What exactly do you mean? This is a REST HTTP API. A basic HTTP connected system should get you started.

Hi Stefan,

Do you know what is The RSA private key in .PEM format while creating CS for share point through Client Credentials - Entra Id from Appian.


Thanks,

Ganesh

The internet has all the knowledge you need, and is better in describing it than I am.

I copied your question into an LLM:

The RSA private key in .PEM format is a base64-encoded representation of a private key used in RSA encryption. When creating a client secret (CS) for SharePoint through Client Credentials with Azure Active Directory (Entra ID) from Appian, you typically need to generate a key pair (public and private keys) for authentication purposes.

### Steps to Create an RSA Private Key in .PEM Format:

1. **Generate RSA Key Pair**: You can use tools like OpenSSL to generate an RSA key pair. The command to generate a 2048-bit RSA private key is:

```bash
openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048
```

2. **Convert to PEM Format**: The private key generated will typically be in PEM format by default. The `.pem` file will contain the private key in a base64-encoded format, enclosed between `-----BEGIN PRIVATE KEY-----` and `-----END PRIVATE KEY-----`.

3. **Use the Private Key**: When configuring your application in Appian or Azure, you will use this private key to authenticate against Azure AD. The public key derived from this private key can be uploaded to Azure AD as part of the application registration.

### Example of a PEM File:

Here’s what a typical RSA private key in PEM format looks like:

```
-----BEGIN PRIVATE KEY-----
MIIEvQIBADANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQ...
... (base64 encoded data) ...
-----END PRIVATE KEY-----
```

### Important Notes:

- **Security**: Keep your private key secure and do not share it. If someone gains access to your private key, they can impersonate your application.
- **Public Key**: You will need to extract the public key from the private key to register it in Azure AD. This can also be done using OpenSSL:

```bash
openssl rsa -in private_key.pem -pubout -out public_key.pem
```

- **App Registration**: When you register your application in Azure AD, you will need to provide the public key and configure the necessary permissions for SharePoint access.

By following these steps, you can create and manage RSA keys for secure authentication in your applications.
