From: lei he <helei.sig11@xxxxxxxxxxxxx> This patch supports the ECDSA algorithm for virtio-crypto: 1. fixed the problem that the max_signature_size of ECDSA is incorrectly calculated. 2. make pkcs8_private_key_parser can identify ECDSA private keys. 3. implement ECDSA algorithm for virtio-crypto device lei he (4): crypto: fix the calculation of max_size for ECDSA crypto: pkcs8 parser support ECDSA private keys crypto: remove unused field in pkcs8_parse_context virtio-crypto: support ECDSA algorithm crypto/Kconfig | 1 + crypto/Makefile | 2 + crypto/akcipher.c | 10 + crypto/asymmetric_keys/pkcs8.asn1 | 2 +- crypto/asymmetric_keys/pkcs8_parser.c | 46 +++- crypto/ecdsa.c | 3 +- crypto/ecdsa_helper.c | 45 +++ .../virtio/virtio_crypto_akcipher_algs.c | 259 ++++++++++++++++-- include/crypto/internal/ecdsa.h | 15 + include/linux/asn1_encoder.h | 2 + lib/asn1_encoder.c | 3 +- 11 files changed, 360 insertions(+), 28 deletions(-) create mode 100644 crypto/ecdsa_helper.c create mode 100644 include/crypto/internal/ecdsa.h -- 2.20.1
