EnvelopedCms()
- Source:
- EnvelopedCms.cs
- Source:
- EnvelopedCms.cs
Initializes a new instance of the EnvelopedCms class with default values.
public:
EnvelopedCms();public EnvelopedCms ();Public Sub New ()Remarks
The EnvelopedCms class has the following default property values:
| Property | Default value |
|---|---|
| ContentInfo | Content Type: 1.2.840.113549.1.7.1 (data) Length: zero |
| ContentEncryptionAlgorithm | 1.2.840.113549.3.7 (RSA_DES_EDE3_CBC) or 2.16.840.1.101.3.4.1.42 (AES-256-CBC) |
The default SubjectIdentifierType for recipients is IssuerAndSerialNumber.
On .NET Framework, the default symmetric encryption algorithm is determined by the version of the .NET Framework that the application executable was built against. Starting with .NET Framework 4.8, the default algorithm is AES-256 in CBC mode; in prior versions, the default is TripleDES (DES3-EDE) in CBC mode.
On .NET Core, the default symmetric encryption algorithm is determined by the version of the System.Security.Cryptography.Pkcs assembly that is loaded. Starting with the 4.6.0 version of the System.Security.Cryptography.Pkcs NuGet package, the default algorithm is AES-256 in CBC mode; in prior versions, the default is TripleDES (DES3-EDE) in CBC mode.
