KERB_CRYPTO_KEY structure (ntsecapi.h)

The KERB_CRYPTO_KEY structure contains information about a Kerberos cryptographic session key.

Syntax

typedef struct KERB_CRYPTO_KEY {
  LONG   KeyType;
  ULONG  Length;
  PUCHAR Value;
} KERB_CRYPTO_KEY, *PKERB_CRYPTO_KEY;

Members

KeyType

Indicates the type of session key stored in the structure. It can be one of the following values.

Value	Meaning
KERB_ETYPE_DES_CBC_CRC	Use DES encryption in cipher-block-chaining mode with a CRC-32 checksum.
KERB_ETYPE_DES_CBC_MD4	Use DES encryption in cipher-block-chaining mode with a MD4 checksum.
KERB_ETYPE_DES_CBC_MD5	Use DES encryption in cipher-block-chaining mode with a MD5 checksum.
KERB_ETYPE_NULL	Use no encryption.
KERB_ETYPE_RC4_HMAC_NT	Use the RC4 stream cipher with a hash-based Message Authentication Code (MAC).
KERB_ETYPE_RC4_MD4	Use the RC4 stream cipher with the MD4 hash function.

 

Values greater than 127 are reserved for local values and may change without notice.

Length

Specifies the length, in bytes, of the cryptographic session key.

Value

Contains the cryptographic session key.
