· Windows OS. Important: Microsoft File Checksum Integrity Verifier (FCIV) utility is an unsupported command-line utility that computes MD5 cryptographic hashes for files. FCIV runs on Windows , Windows XP, and Windows Server If you're using a Windows operating system, you can use Microsoft PowerShell Utility’s Get-FileHash cmdlet to calculate MD5 digest, like this. Regardless I'm looking for a way to get the checksum without downloading the file. 0 0. Share. skatamatic Practically a Posting Shark. 9 Years Ago. That seems kind of silly to me. The point of a checksum is to verify the legitimacy of a file after downloading it. If you're getting the checksum before downloading the file it's no different. · AWS's documentation of ETag says. The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object www.doorway.rus: 2.
-c, --check=file: file should be the output of a former run of md5sum. The file has in each line the MD5 sum, a binary/text flag, and a file name. This file will be opened (with each possible relative path) and the message digest is computed. If it is not the same as given in this line it will be marked as failed.-t, --text.

The entity tag is a hash of the object. The ETag reflects changes only to the contents of an object, not its metadata. The ETag may or may not be an MD5 digest of the object data. Download¶ The AWS CLI will attempt to verify the checksum of downloads when possible, based on the ETag header returned from a GetObject request that's performed whenever the AWS CLI downloads objects from S3. If the calculated MD5 checksum does not match the expected checksum, the file is deleted and the download is retried.
