NAME¶

RSAENH_CPGetKeyParam (RSAENH.@)

SYNOPSIS¶

BOOL RSAENH_CPGetKeyParam
(
HCRYPTPROV hProv,
HCRYPTKEY hKey,
DWORD dwParam,
BYTE* pbData,
DWORD* pdwDataLen,
DWORD dwFlags
)

DESCRIPTION¶

Query a key parameter.

PARAMS¶

hProv [In] The key container, which the key belongs to. hHash [In] The key object that is to be queried. dwParam [In] Specifies the parameter that is to be queried. pbData [In] Pointer to the buffer where the parameter value will be stored. pdwDataLen [In/Out] I: Buffer length at pbData, O: Length of the parameter value. dwFlags [In] None currently defined.

RETURNS¶

Success: TRUE Failure: FALSE.

NOTES¶

Defined dwParam types are: - KP_MODE: Values MODE_CBC, MODE_ECB, MODE_CFB. - KP_MODE_BITS: Shift width for cipher feedback mode. (Currently ignored by Microsoft(tm) CSP's - always eight) - KP_PERMISSIONS: Or'ed combination of CRYPT_ENCRYPT, CRYPT_DECRYPT, CRYPT_EXPORT, CRYPT_READ, CRYPT_WRITE, CRYPT_MAC - KP_IV: Initialization vector. - KP_KEYLEN: Bitwidth of the key. - KP_BLOCKLEN: Size of a block cipher block. - KP_SALT: Salt value.

IMPLEMENTATION¶

Not declared in a Wine header. The function is either undocumented, or missing from Wine. Implemented in "dlls/rsaenh/rsaenh.c". Debug channel "crypt".
