Oct 23, 2008 Hi all, The other day a colleague of mine asked me if I had a.NET version of the C sample in How to generate key pairs, encrypt and decrypt data with CryptoAPI post. C sample calls CryptoAPI directly (and you know we can do the same thing in.NET through P/Invoke), but the idea was to use.

C sample calls CryptoAPI directly (and you know we can do the same thing in.NET through P/Invoke), but the idea was to use System.Security classes in order to get a pure.NET solution.

We'll generate one that is 512 bytes in length, which should be plenty for encryption of a text string. Here is the key generation code.

The data protection system employs a discovery mechanism by default to determine how cryptographic keys should be encrypted at rest. The developer can override the discovery mechanism and manually specify how keys should be encrypted at rest.
![]()
Warning
If you specify an explicit key persistence location, the data protection system deregisters the default key encryption at rest mechanism. Consequently, keys are no longer encrypted at rest. We recommend that you specify an explicit key encryption mechanism for production deployments. The encryption-at-rest mechanism options are described in this topic.
Azure Key Vault
To store keys in Azure Key Vault, configure the system with ProtectKeysWithAzureKeyVault in the
Startup class:
For more information, see Configure ASP.NET Core Data Protection: ProtectKeysWithAzureKeyVault.
Windows DPAPI
Only applies to Windows deployments.
Where To Find Encryption Key
When Windows DPAPI is used, key material is encrypted with CryptProtectData before being persisted to storage. DPAPI is an appropriate encryption mechanism for data that's never read outside of the current machine (though it's possible to back these keys up to Active Directory; see DPAPI and Roaming Profiles). To configure DPAPI key-at-rest encryption, call one of the ProtectKeysWithDpapi extension methods:
If
ProtectKeysWithDpapi is called with no parameters, only the current Windows user account can decipher the persisted key ring. You can optionally specify that any user account on the machine (not just the current user account) be able to decipher the key ring:
X.509 certificate
Adobe cs5 product key generator software. If the app is spread across multiple machines, it may be convenient to distribute a shared X.509 certificate across the machines and configure the hosted apps to use the certificate for encryption of keys at rest:
Due to .NET Framework limitations, only certificates with CAPI private keys are supported. See the content below for possible workarounds to these limitations.
Windows DPAPI-NG
This mechanism is available only on Windows 8/Windows Server 2012 or later.
Beginning with Windows 8, Windows OS supports DPAPI-NG (also called CNG DPAPI). Nero burning rom key generator 10. For more information, see About CNG DPAPI.
The principal is encoded as a protection descriptor rule. In the following example that calls ProtectKeysWithDpapiNG, only the domain-joined user with the specified SID can decrypt the key ring:
There's also a parameterless overload of
ProtectKeysWithDpapiNG . Use this convenience method to specify the rule 'SID={CURRENT_ACCOUNT_SID}', where CURRENT_ACCOUNT_SID is the SID of the current Windows user account:
In this scenario, the AD domain controller is responsible for distributing the encryption keys used by the DPAPI-NG operations. The target user can decipher the encrypted payload from any domain-joined machine (provided that the process is running under their identity).
Certificate-based encryption with Windows DPAPI-NG
If the app is running on Windows 8.1/Windows Server 2012 R2 or later, you can use Windows DPAPI-NG to perform certificate-based encryption. Use the rule descriptor string 'CERTIFICATE=HashId:THUMBPRINT', where THUMBPRINT is the hex-encoded SHA1 thumbprint of the certificate:
Any app pointed at this repository must be running on Windows 8.1/Windows Server 2012 R2 or later to decipher the keys.
Custom key encryption
If the in-box mechanisms aren't appropriate, the developer can specify their own key encryption mechanism by providing a custom IXmlEncryptor.
