Public Overrides Sub Import (rawData As Byte())
Parameters
- rawData
- Byte[]
A byte array containing data from an X.509 certificate.
- Attributes
Remarks
This method can be used to take a raw byte array of an X.509 certificate and populate the X509Certificate2 object with its associated values.
Since this method accepts only a byte array, it can be used only for certificate types that do not require a password, including a Base64-encoded or DER-encoded X.509 certificate or a PFX/PKCS12 certificate. Note that a PFX/PKCS12 certificate can contain more than one certificate. In that case, the first certificate associated with a private key is used or, if no private key is found, the first certificate is used.

Public Overrides Sub Import (fileName As String)
Parameters
- fileName
- String
The name of a certificate.
- Attributes
Remarks
This method uses a certificate file, such as a file with a .cer extension, that represents an X.509 certificate and populates the X509Certificate2 object with the certificate the file contains.
This method can be used with several certificate types, including Base64-encoded or DER-encoded X.509 certificates, PFX/PKCS12 certificates, and signer certificates such as Authenticode. Note that a PFX/PKCS12 certificate can contain more than one certificate. In that case, the first certificate associated with a private key is used or, if no private key is found, the first certificate is used.

Remarks
This method can be used to populate an X509Certificate2 object using a password for the certificate represented by the byte array. The X509KeyStorageFlags value can be used to control where and how to import the private key.
This method accepts a byte array and can be used for certificate types such as Base64-encoded or DER-encoded X.509 certificates or PFX/PKCS12 certificates. Note that a PFX/PKCS12 certificate can contain more than one certificate. In that case, the first certificate associated with a private key is used or, if no private key is found, the first certificate is used.
Important
Never hard code a password within your source code. Hard-coded passwords can be retrieved from an assembly using the Ildasm.exe (IL Disassembler), a hex editor, or by simply opening up the assembly in a text editor such as Notepad.exe.
