= Configuring the DPA to override Kopia hashing, encryption, and splitter algorithms
|
|
|
|
[role="_abstract"]
|
|
You can use an {oadp-first} option to override the default Kopia algorithms for hashing, encryption, and splitter to improve Kopia performance or to compare performance metrics. You can set the following environment variables in the `spec.configuration.velero.podConfig.env` section of the DPA:
|
|
|
|
* `KOPIA_HASHING_ALGORITHM`
|
|
* `KOPIA_ENCRYPTION_ALGORITHM`
|
|
* `KOPIA_SPLITTER_ALGORITHM`
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the {oadp-short} Operator.
|
|
* You have created the secret by using the credentials provided by the cloud provider.

<3> Include the `csi` plugin.
|
|
<4> Specify a hashing algorithm. For example, `BLAKE3-256`.
|
|
<5> Specify an encryption algorithm. For example, `CHACHA20-POLY1305-HMAC-SHA256`.
|
|
<6> Specify a splitter algorithm. For example, `DYNAMIC-8M-RABINKARP`.
