NAME

SystemFunction004 (ADVAPI32.@)

 NTSTATUS SystemFunction004
 (
  const struct ustring* in,
  const struct ustring* key,
  struct ustring*       out
 )

Encrypts a block of data with DES in ECB mode, preserving the length.

data	[In]	data to encrypt.
`key`	[In]	`key` data (up to `7` bytes).
output	[Out]	buffer to receive encrypted data.

Success: STATUS_SUCCESS

Failure: STATUS_BUFFER_TOO_SMALL if the output buffer is too small

Failure: STATUS_INVALID_PARAMETER_2 if the key is zero length.

Encrypt buffer size should be input size rounded up to 8 bytes plus an extra 8 bytes.

Not declared in a Wine header. The function is either undocumented, or missing from Wine.
