# Checksum
|
||
|
|
|
||
|
|
This script can generate checksums from md5, sha1, sha224, sha256, sha384, and sha512.
|
||
|
|
Additionally, for another layer of secret it can create signed checksums using HMAC and a provided secret.
|
||
|
|
Lastly, to provide actual value to the script it can also verify if a checksum matches the file it was generated from.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
Generate a sha1 checksum
|
||
|
|
```
|
||
|
|
python checksum.py -H sha1 -f test.txt -g
|
||
|
|
# b29d28bc5239dbc2689215811b2a73588609f301
|
||
|
|
```
|
||
|
|
|
||
|
|
Generate a signature
|
||
|
|
```
|
||
|
|
python checksum.py -f test.txt -s secret
|
||
|
|
# 3YYMCthY4hFxQj1wPF3uAg==
|
||
|
|
```
|
||
|
|
|
||
|
|
Verify a checksum
|
||
|
|
```
|
||
|
|
python -H sha1 -f test.txt -v b29d28bc5239dbc2689215811b2a73588609f301
|
||
|
|
```
|
||
|
|
|
||
|
|
Verify a signature
|
||
|
|
```
|
||
|
|
python -f test.txt -s secret -v 3YYMCthY4hFxQj1wPF3uAg==
|
||
|
|
```
