# Hash Functions

> The hashing algorithms Convoy supports for signing payloads.

We have found that most implementations use `SHA256` & `SHA512`. However, Convoy also supports the following hash functions:

* `MD5`
* `SHA1`
* `SHA224`
* `SHA256`
* `SHA384`
* `SHA512`
* `SHA3_224`
* `SHA3_256`
* `SHA3_384`
* `SHA3_512`
* `SHA512_224`
* `SHA512_256`

These are used together with your endpoint [secret](/glossary/secrets) to sign event payloads.
