I have some doubts regarding AEAD ciphersuites and I need some clarification. In the following ciphersuites list:
dhe_rsa_aes_128_sha dhe_rsa_aes_256_sha ecdhe_ecdsa_aes_128_gcm_sha256 ecdhe_ecdsa_aes_128_sha ecdhe_ecdsa_aes_256_gcm_sha384 ecdhe_ecdsa_aes_256_sha ecdhe_ecdsa_chacha20_poly1305_sha256 ecdhe_rsa_aes_128_gcm_sha256 ecdhe_rsa_aes_128_sha ecdhe_rsa_aes_256_gcm_sha384 ecdhe_rsa_aes_256_sha ecdhe_rsa_chacha20_poly1305_sha256 rsa_aes_128_sha rsa_aes_256_sha rsa_des_ede3_sha
I have some questions:
Can you help me identify the ciphersuites that provide Authenticate Encryption with Associated Data (AEAD) from those that do not?
Are GCM and Poly1305 ciphers indicates AEAD and the rest of ciphers do not provide it? Can you list all the AEAD algorithms?
Is it always the case that AE ciphersuites must be also Forward Secrecy ciphersuites? or there is no relation that binds the two?
Is Authenticated Encryption (AE) is the same AEAD? or they are different terms?
