メソッドの詳細

sign

public void sign(byte[] data,
                 int offset,
                 int length,
                 CommonServerMessageBlock request,
                 CommonServerMessageBlock response)

Performs MAC signing of the SMB. This is done as follows. The signature field of the SMB is overwritten with the sequence number; The MD5 digest of the MAC signing key + the entire SMB is taken; The first 8 bytes of this are placed in the signature field.

定義:

sign インタフェース内 SMBSigningDigest

パラメータ:

data - The data.

offset - The starting offset at which the SMB header begins.

length - The length of the SMB data starting at offset.

request - request message

response - response message

verify

public boolean verify(byte[] data,
                      int offset,
                      int length,
                      int extraPad,
                      CommonServerMessageBlock msg)

Performs MAC signature verification. This calculates the signature of the SMB and compares it to the signature field on the SMB itself.

定義:

verify インタフェース内 SMBSigningDigest

パラメータ:

data - The data.

offset - The starting offset at which the SMB header begins.

extraPad - extra padding to include in signature

msg - The message to verify

戻り値:

whether verification was unsuccessful
