Cryptography Constants
The following constants are used by cryptography functions and defined in Wincrypt.h. Cryptography constants are categorized according to usage as follows.
| Constant | Description |
|---|---|
| Constants for CryptEncodeObject and CryptDecodeObject | Predefined constants used with Abstract Syntax Notation One (ASN.1) encode and decode operations. |
| Constants for Netscape Extensions | Predefined constants used for Netscape certificate extensions. This section provides details on the use of these extensions with ASN.1 encoding and decode operations. |
| Cryptographic Provider Names | Predefined string constants for the names of common cryptographic service providers (CSPs). |
| MAXUIDLEN | A numeric constant that specifies the maximum number of characters that some of the Microsoft cryptographic providers will use when obtaining the user ID. |
| Private Key Caching Constants | Constants that represent registry entries that control private key caching by a CSP. |
| Protocol Flags | Predefined constants for cryptography protocols. |
