在为Windows操作系统中的大文件计算SHA-1哈希时,Python崩溃

Zipped script here

要么：

import sys
import msvcrt
import hashlib

#Print the file name (and its LOCATIOn) to be hashed  
print 'File:  ' + str(sys.argv[1])

#Set "SHA1Hash" equal to SHA-1 hash
SHA1Hash = hashlib.sha1()

#Open file specified by "sys.argv[1]" in read only (r) and binary (b) mode
File = open(sys.argv[1],'rb')

#Get the SHA-1 hash for the contents of the specified file
SHA1Hash.update(File.read())

#Close the file
File.close()

#Set "SHA1HashBase16" equal to the hexa@R_450_6221@l of "SHA1Hash"
SHA1HashBase16 = SHA1Hash.hexdigest()

#Print the SHA-1 (hexa@R_450_6221@l) hash of the file
print 'SHA-1: ' + SHA1HashBase16

#Make a blank line
print ' '

#Print "Press any key to conTinue..."
print 'Press any key to conTinue...'

#"Press any key to conTinue..." delay
char=0
while not char:
    char=msvcrt.getch()

使用python脚本计算大文件的SHA-1哈希值.感谢Ignacio Vazquez-Abrams指出错误和Tom Zych的代码.

使用简单地拖放要在脚本顶部进行哈希处理的文件.或者,您可以使用命令提示符,使用：

SHA-1HashGen.py Path&File

SHA-1HashGen.py是脚本的文件名,Path& File是要散列的文件的路径和文件名.

或者将脚本放入SendTo文件夹(在Windows操作系统中; sHell：sendto)以将其作为右键单击选项.
