This article contains details on validating the origin and integrity of the latest version of Transmit 5
Transmit 5.8.2 Checksum
The SHA256 checksum of the
Transmit 5.8.2.zip archive, available at https://download.panic.com/transmit/Transmit 5.8.2.zip is:
Validating the Checksum
- Download Transmit 5.8.2.zip
- Run the following command in Terminal to compute the checksum of your copy:
$ shasum -a 256 ~/Downloads/Transmit\ 5.8.2.zip
If the hash portion of the command output matches the checksum above:
d1ccc52f08cb2980548675a456d301d74613d7f48461945b5f766676361ad7a0 /Users/panic/Downloads/Transmit 5.8.2.zip
you can be sure that your copy of the download is identical to the version on our website.
Unfortunately, validating the checksum alone does not guarantee that the contents of
Transmit 5.8.2.zip haven't changed since we posted it*. However, with one extra step you can also determine with certainty that the checksum above, and therefore the contents of the ZIP, originated from Panic.
*Why not? In the very unlikely circumstance that a malicious actor replaced the ZIP archive on our website and modified the contents of this article using a new SHA256 hash, the checksum could still validate.
Transmit 5.8.2 Checksum Signature
Using our public profile on Keybase, we have PGP-signed the SHA256 checksum from above:

Validating the Signature
- Copy the entire PGP message above, including
-----BEGIN PGP MESSAGE-----and
-----END PGP MESSAGE-----
- Paste the contents into the Message to verify box on Keybase
- Click Verify
Most importantly, Keybase should indicate that the message was signed by Panic:
Additionally, the resulting Signed Text should match our original checksum:
If both items match, you can be sure that the checksum in this article originated from Panic.
Putting it all together
By using two factors of validation:
- A checksum which ensures that your copy of
Transmit 5.8.2.zipis identical to the copy on our website
- A PGP signature which ensures that the checksum originated from Panic
you can be sure that you are installing the release that we originally posted.
