Gilles Peskine	07c91f5df3	Add notes about the purpose and usage of auxiliary header files	2018-09-12 16:41:11 +03:00
Gilles Peskine	af3baabd05	Define max sizes for MAC and signatures ... This requires defining a maximum RSA key size, since the RSA key size is the signature size. Enforce the maximum RSA key size when importing or generating a key.	2018-09-12 16:41:11 +03:00
Gilles Peskine	49cee6c582	Move implementation-dependent size macros to crypto_sizes.h ... Macros such as PSA_HASH_SIZE whose definitions can be the same everywhere except in implementations that support non-standard algorithms remain in crypto.h, at least for the time being.	2018-09-12 16:41:11 +03:00
Gilles Peskine	0cad07c2fb	New header crypto_sizes.h ... This header will contain macros that calculate buffer sizes, whose semantics are standardized but whose definitions are implementation-specific because they depend on the available algorithms and on some permitted buffer size tolerances. Move size macros from crypto_struct.h to crypto_sizes.h, because these definitions need to be available both in the frontend and in the backend, whereas structures have different contents.	2018-09-12 16:41:11 +03:00
