Thanks. I've added the chacha ciphersuites into gnutls, and run the TLS
benchmarks (with AES acceleration disabled):
RSA_AES_128_GCM_SHA256 84.49 MB/sec
RSA_AES_128_CCM 65.35 MB/sec
RSA_CHACHA20_POLY1305 200.33 MB/sec
When AESNI/PCLMUL are enabled:
RSA_AES_128_GCM_SHA256 1.19 GB/sec
RSA_AES_128_CCM 0.27 GB/sec
RSA_CHACHA20_POLY1305 0.20 GB/sec
I guess chacha will be good for smaller systems which have no hw AES
acceleration.
One small comment. I liked the ccm_encrypt_message() in ccm.h and would
be nice if it would be come the default interface provided by all AEAD
ciphers in nettle.
regards,
Nikos
