+# SRP6a-sha512 library
+
+## About
+
+This library is based on Stanford's Secure Remote Password (SRP) protocol
+implementation, or more precise on the `libsrp` part thereof.
+The entire source code for the SRP project can be obtained from [here](https://github.com/secure-remote-password/stanford-srp).
+
+It has been adapted to the needs of the libimobiledevice project, and
+contains just a part of the original code; it only supports the SRP6a
+client method which has been modified to use SHA512 instead of SHA1.
+The only supported SRP method is `SRP6a_sha512_client_method()`.
+Besides that, support for MbedTLS has been added.
+
+Also, all server-side code has been removed, and the client-side code
+has been reduced to a minimum, so that basically only the following
+functions remain operational:
+
+- `SRP_initialize_library`
+- `SRP_new`
+- `SRP_free`
+- `SRP_set_user_raw`
+- `SRP_set_params`
+- `SRP_set_auth_password`
+- `SRP_gen_pub`
+- `SRP_compute_key`
+- `SRP_respond`
+- `SRP_verify`
+
+Anything else has not been tested and must be considered non-functional.

+## License
+
+The license of the original work does still apply and can be found in the
+LICENSE file that comes with the code.
