Coda 2.7.3 Checksum

The SHA256 checksum of the Coda 2.7.3.zip archive, available at https://download.panic.com/coda/Coda 2.7.3.zip is:

b0a8cf33f725f16268b92b1c68d78879b039f4c4d8a09eb74325b8767d250181

Validating the Checksum

  1. Download Coda 2.7.3.zip
  2. Run the following command in Terminal to compute the checksum of your copy:
$ shasum -a 256 ~/Downloads/Coda\ 2.7.3.zip

If the hash portion of the command output matches the checksum above:

b0a8cf33f725f16268b92b1c68d78879b039f4c4d8a09eb74325b8767d250181  /Users/panic/Downloads/Coda 2.7.3.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 Coda 2.7.3.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.

Coda 2.7.3 Checksum Signature

Using our public profile on Keybase, we have PGP-signed the SHA256 checksum from above:

-----END PGP MESSAGE-----

Validating the Signature

  1. Copy the entire PGP message above, including -----BEGIN PGP MESSAGE----- and -----END PGP MESSAGE-----
  2. Paste the contents into the Message to verify box on Keybase
  3. Click Verify

Most importantly, Keybase should indicate that the message was signed by Panic:

Verification badge from Keybase

Additionally, the resulting Signed Text should match our original checksum:

b0a8cf33f725f16268b92b1c68d78879b039f4c4d8a09eb74325b8767d250181

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 Coda 2.7.3.zip is 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.
