@SHA1

String mode:        @SHA1[s,string[,start[,length]]]

File mode:        @SHA1[[f,]filename[,start[,length]]]

Binary mode:        @SHA1[[b,]handle[,start[,length]]]

 

Returns the SHA1 checksum of the characters in string, the contents of the file filename, or the contents of the binary buffer. If the first parameter is s for a string, any leading or trailing whitespace characters in string are included. If the first argument is a b, the filename argument should be the handle returned by @BALLOC.

 

The first parameter determines whether the output is in upper or lower case:

 

s or f or blower case
S or F or Bupper case

 

The optional start parameter specifies the starting position in the binary buffer or file (in bytes, defaulting to 0).

 

The optional length parameter specifies the length of the buffer to hash (in bytes, defaulting to 0).

 

Example:

 

echo %@sha1[c:\windows\notepad.exe]
