Hi,

I have a TLS 1.0 client which supports AES cipher suites defined in RFC3268.
However, when it connects to a TLS server using OpenSSL 0.97. It gets a TLS
fatal alert, 20 (bad record MAC). I saw the version is 3.1 and the cipher
suite ID is 0x00 0x35 (TLS_RSA_WITH_AES_256_CBC_SHA) in the server hello
message. Does anyone know if TLS_RSA_WITH_AES_256_CBC_SHA is supported in
OpenSSL 0.97? Is there any problem with AES cipher suites? I searched
openssl-users and openssl-dev archives and found there was a bug in the AES
decryption but it was fixed in a recent patch. Is the bug in OpenSSL 0.97?
Does it affect the AES cipher suites in TLS 1.0? My TLS client successfully
connects to the same server using TLS_RSA_WITH_3DES_EDE_CBC_SHA (0x00 0x0a).
