+## ed25519
+
+Source: https://github.com/orlp/ed25519
+Based on commit 7fa6712ef5d581a6981ec2b08ee623314cd1d1c4.
+[LICENCE](ed25519/LICENSE)
+
+The original source has not been modified, except that the file `test.c`
+and the contained DLL files have been removed. To allow building within
+libimobiledevice, a `Makefile.am` has been added.

+## libsrp6a-sha512
+
+Source: https://github.com/secure-remote-password/stanford-srp
+Based on commit 587900d32777348f98477cb25123d5761fbe3725.
+[LICENCE](libsrp6a-sha512/LICENSE)
+
+For the usage within libimobiledevice, only [libsrp](https://github.com/secure-remote-password/stanford-srp/tree/master/libsrp)
+has been used as a basis.
+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,
+hence the name was changed to `libsrp6a-sha512`.
+More details about the modifications can be found in [libsrp6a-sha512/README.md](libsrp6a-sha512/README.md).

+Ed25519
+=======
+
+This is a portable implementation of [Ed25519](http://ed25519.cr.yp.to/) based
+on the SUPERCOP "ref10" implementation. Additionally there is key exchanging
+and scalar addition included to further aid building a PKI using Ed25519. All
+code is licensed under the permissive zlib license.
+
+All code is pure ANSI C without any dependencies, except for the random seed
+generation which uses standard OS cryptography APIs (`CryptGenRandom` on
+Windows, `/dev/urandom` on nix). If you wish to be entirely portable define
+`ED25519_NO_SEED`. This disables the `ed25519_create_seed` function, so if your
+application requires key generation you must supply your own seeding function
+(which is simply a 256 bit (32 byte) cryptographic random number generator).
+
+
+Performance
+-----------
+
+On a Windows machine with an Intel Pentium B970 @ 2.3GHz I got the following
+speeds (running on only one a single core):
+
+ Seed generation: 64us (15625 per second)
+ Key generation: 88us (11364 per second)
+ Message signing (short message): 87us (11494 per second)
+ Message verifying (short message): 228us (4386 per second)
+ Scalar addition: 100us (10000 per second)
+ Key exchange: 220us (4545 per second)
+
+The speeds on other machines may vary. Sign/verify times will be higher with
+longer messages. The implementation significantly benefits from 64 bit
+architectures, if possible compile as 64 bit.
+
+
+Usage
+-----
+
+Simply add all .c and .h files in the `src/` folder to your project and include
+`ed25519.h` in any file you want to use the API. If you prefer to use a shared
+library, only copy `ed25519.h` and define `ED25519_DLL` before importing.
+
+There are no defined types for seeds, private keys, public keys, shared secrets
+or signatures. Instead simple `unsigned char` buffers are used with the
+following sizes:
+
+```c
+unsigned char seed[32];
+unsigned char signature[64];
+unsigned char public_key[32];
+unsigned char private_key[64];
+unsigned char scalar[32];
+unsigned char shared_secret[32];
+```
+
+API
+---
+
+```c
+int ed25519_create_seed(unsigned char *seed);
+```
+
+Creates a 32 byte random seed in `seed` for key generation. `seed` must be a
+writable 32 byte buffer. Returns 0 on success, and nonzero on failure.
+
+```c
+void ed25519_create_keypair(unsigned char *public_key, unsigned char *private_key,
+ const unsigned char *seed);
+```
+
+Creates a new key pair from the given seed. `public_key` must be a writable 32
+byte buffer, `private_key` must be a writable 64 byte buffer and `seed` must be
+a 32 byte buffer.
+
+```c
+void ed25519_sign(unsigned char *signature,
+ const unsigned char *message, size_t message_len,
+ const unsigned char *public_key, const unsigned char *private_key);
+```
+
+Creates a signature of the given message with the given key pair. `signature`
+must be a writable 64 byte buffer. `message` must have at least `message_len`
+bytes to be read.
+
+```c
+int ed25519_verify(const unsigned char *signature,
+ const unsigned char *message, size_t message_len,
+ const unsigned char *public_key);
+```
+
+Verifies the signature on the given message using `public_key`. `signature`
+must be a readable 64 byte buffer. `message` must have at least `message_len`
+bytes to be read. Returns 1 if the signature matches, 0 otherwise.
+
+```c
+void ed25519_add_scalar(unsigned char *public_key, unsigned char *private_key,
+ const unsigned char *scalar);
+```
+
+Adds `scalar` to the given key pair where scalar is a 32 byte buffer (possibly
+generated with `ed25519_create_seed`), generating a new key pair. You can
+calculate the public key sum without knowing the private key and vice versa by
+passing in `NULL` for the key you don't know. This is useful for enforcing
+randomness on a key pair by a third party while only knowing the public key,
+among other things. Warning: the last bit of the scalar is ignored - if
+comparing scalars make sure to clear it with `scalar[31] &= 127`.
+
+
+```c
+void ed25519_key_exchange(unsigned char *shared_secret,
+ const unsigned char *public_key, const unsigned char *private_key);
+```
+
+Performs a key exchange on the given public key and private key, producing a
+shared secret. It is recommended to hash the shared secret before using it.
+`shared_secret` must be a 32 byte writable buffer where the shared secret will
+be stored.
+
+Example
+-------
+
+```c
+unsigned char seed[32], public_key[32], private_key[64], signature[64];
+unsigned char other_public_key[32], other_private_key[64], shared_secret[32];
+const unsigned char message[] = "TEST MESSAGE";
+
+/* create a random seed, and a key pair out of that seed */
+if (ed25519_create_seed(seed)) {
+ printf("error while generating seed\n");
+ exit(1);
+}
+
+ed25519_create_keypair(public_key, private_key, seed);
+
+/* create signature on the message with the key pair */
+ed25519_sign(signature, message, strlen(message), public_key, private_key);
+
+/* verify the signature */
+if (ed25519_verify(signature, message, strlen(message), public_key)) {
+ printf("valid signature\n");
+} else {
+ printf("invalid signature\n");
+}
+
+/* create a dummy keypair to use for a key exchange, normally you'd only have
+the public key and receive it through some communication channel */
+if (ed25519_create_seed(seed)) {
+ printf("error while generating seed\n");
+ exit(1);
+}
+
+ed25519_create_keypair(other_public_key, other_private_key, seed);
+
+/* do a key exchange with other_public_key */
+ed25519_key_exchange(shared_secret, other_public_key, private_key);
+
+/*
+ the magic here is that ed25519_key_exchange(shared_secret, public_key,
+ other_private_key); would result in the same shared_secret
+*/

+Write p=2^255-19; q=floor(h/p).
+Basic claim: q = floor(2^(-255)(h + 19 2^(-25)h9 + 2^(-1))).
+
+Proof:
+ Have |h|<=p so |q|<=1 so |19^2 2^(-255) q|<1/4.
+ Also have |h-2^230 h9|<2^231 so |19 2^(-255)(h-2^230 h9)|<1/4.
+
+ Write y=2^(-1)-19^2 2^(-255)q-19 2^(-255)(h-2^230 h9).
+ Then 0<y<1.
+
+ Write r=h-pq.
+ Have 0<=r<=p-1=2^255-20.
+ Thus 0<=r+19(2^-255)r<r+19(2^-255)2^255<=2^255-1.
+
+ Write x=r+19(2^-255)r+y.
+ Then 0<x<2^255 so floor(2^(-255)x) = 0 so floor(q+2^(-255)x) = q.
+
+ Have q+2^(-255)x = 2^(-255)(h + 19 2^(-25) h9 + 2^(-1))
+ so floor(2^(-255)(h + 19 2^(-25) h9 + 2^(-1))) = q.

+# 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.

+ * WARNING: depending on the particular platform, raw_truerand()
+ * output may be biased or correlated. In general, you can expect
+ * about 16 bits of "pseudo-entropy" out of each 32 bit word returned
+ * by truerand(), but it may not be uniformly diffused. You should
+ * raw_therefore run the output through some post-whitening function
+ * (like MD5 or DES or whatever) before using it to generate key
+ * material. (RSAREF's random package does this for you when you feed
+ * raw_truerand() bits to the seed input function.)
+ *
+ * The application interface, for 8, 16, and 32 bit properly "whitened"
+ * random numbers, can be found in trand8(), trand16(), and trand32().
+ * Use those instead of calling raw_truerand() directly.
+ *
+ * The basic idea here is that between clock "skew" and various
+ * hard-to-predict OS event arrivals, counting a tight loop will yield
+ * a little (maybe a third of a bit or so) of "good" randomness per
+ * interval clock tick. This seems to work well even on unloaded
+ * machines. If there is a human operator at the machine, you should
+ * augment truerand with other measure, like keyboard event timing.
+ * On server machines (e.g., when you need to generate a
+ * Diffie-Hellman secret) truerand alone may be good enough.
+ *
+ * Test these assumptions on your own platform before fielding a
+ * system based on this software or these techniques.
+ *
+ * This software seems to work well (at 10 or so bits per
+ * raw_truerand() call) on a Sun Sparc-20 under SunOS 4.1.3 and on a
+ * P100 under BSDI 2.0. You're on your own elsewhere.
