+# Verifying OTP release integrity
+
+All OTP releases are cryptographically signed, to allow
+you to verify the integrity if you choose to.
+
+Releases are signed with [Signify](https://man.openbsd.org/signify.1),
+with [the public key in the main repository](https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/SIGNING_KEY.pub)
+
+Release URLs will always be of the form
+
+```
+https://akkoma-updates.s3-website.fr-par.scw.cloud/{branch}/akkoma-{flavour}.zip
+```
+
+Where branch is usually `stable` or `develop`, and `flavour` is
+the one [that you detect on install](../otp_en/#detecting-flavour).
+
+So, for an AMD64 stable install, your update URL will be
+
+```
+https://akkoma-updates.s3-website.fr-par.scw.cloud/stable/akkoma-amd64.zip
+```
+
+To verify the integrity of this file, we have two helper files
+
+```
+# Checksums
+https://akkoma-updates.s3-website.fr-par.scw.cloud/{branch}/akkoma-{flavour}.zip.sha256
+
+# Signify signature of the hashes
+https://akkoma-updates.s3-website.fr-par.scw.cloud/{branch}/akkoma-{flavour}.zip.sha256.sig
+```
+
+Thus, to upgrade manually, with integrity checking, consider the following script:
+
+```bash
+#!/bin/sh
+set -eo pipefail
+
+export FLAVOUR=amd64
+export BRANCH=stable
+
+# Fetch signing key
+wget https://akkoma.dev/AkkomaGang/akkoma/src/branch/develop/SIGNING_KEY.pub -o AKKOMA_SIGNING_KEY.pub
+
+# Download zip file and sig files
+wget https://akkoma-updates.s3-website.fr-par.scw.cloud/$BRANCH/akkoma-$FLAVOUR{.zip,.zip.sha256,.zip.sha256.sig}
+
+# Verify zip file's sha256 integrity
+sha256sum --check akkoma-$FLAVOUR.zip.sha256
+
+# Verify hash file's integrity
+signify -V -p AKKOMA_SIGNING_KEY.pub -m akkoma-$FLAVOUR.zip.sha256.sig
+
+# We're good, use that URL
+./bin/pleroma_ctl update --zip-url https://akkoma-updates.s3-website.fr-par.scw.cloud/$BRANCH/akkoma-$FLAVOUR.zip
+```
