This series implements ECDSA signature verification for FIT images.
The ECDSA code itself is taken from the Kernel. Currently only supported
way to specify a ECDSA key is to compile it into the binary using
CONFIG_CRYPTO_ECDSA_KEY, taking it from a device tree is not ye
supported.
Changes since v1:
- better split up rsatoc patches
- keep engine support around in rsatoc as it is still needed in many
cases
- Add more cleanup to rsatoc
Sascha Hauer (19):
errno: include string for EOPNOTSUPP
rsatoc: disable deprecated function warnings
rsatoc: remove unnecessary function call
rsatoc: pass EVP_PKEY around
rsatoc: rename rsa_err() to openssl_error()
rsatoc: move engine initialization to engine_get_pub_key()
rsatoc: cleanup error handling
rsatoc: remove unnecessary error check
rsatoc: use non deprecated openssl functions to retrieve RSA params
rsatoc: check error value of gen_key()
rsatoc: rename to keytoc
keytoc: add ecdsa support
keytoc: Let openssl_error() take a format string
keytoc: clarify error messages
malloc: implement free_sensitive()
Add elliptic curve cryptography (ECC) helper functions
crypto: add ECDSA support
crypto: make RSA a visible option
fit: Add ecdsa support
