crypto: sig - Add interface for sign/verify

2023-06-23T08:15:36+00:00

Split out the sign/verify functionality from the existing akcipher interface. Most algorithms in akcipher either support encryption and decryption, or signing and verify. Only one supports both. As a signature algorithm may not support encryption at all, these two should be spearated. For now sig is simply a wrapper around akcipher as all algorithms remain unchanged. This is a first step and allows users to start allocating sig instead of akcipher. Signed-off-by: Herbert Xu

crypto: api - Add crypto_tfm_get

2023-04-20T10:20:04+00:00

Add a crypto_tfm_get interface to allow tfm objects to be shared. They can still be freed in the usual way. This should only be done with tfm objects with no keys. You must also not modify the tfm flags in any way once it becomes shared. Signed-off-by: Herbert Xu Reviewed-by: Simon Horman Signed-off-by: Herbert Xu

crypto: api - Move low-level functions into algapi.h

2023-04-14T10:59:34+00:00

A number of low-level functions were exposed in crypto.h. Move them into algapi.h (and internal.h). Signed-off-by: Herbert Xu

crypto: api - Move MODULE_ALIAS_CRYPTO to algapi.h

2023-03-14T09:06:42+00:00

This is part of the low-level API and should not be exposed to top-level Crypto API users. Signed-off-by: Herbert Xu

crypto: rng - Count error stats differently

2023-03-14T09:06:42+00:00

Move all stat code specific to rng into the rng code. While we're at it, change the stats so that bytes and counts are always incremented even in case of error. This allows the reference counting to be removed as we can now increment the counters prior to the operation. After the operation we simply increase the error count if necessary. This is safe as errors can only occur synchronously (or rather, the existing code already ignored asynchronous errors which are only visible to the callback function). Signed-off-by: Herbert Xu
