ssl - cipher suite specs using TLSv1.2 only and no SSLv3 TLSv1.2:!aNULL:!eNULL -


when using vpn-like connection between 2 servers (not web servers or it), besides authentication enable encryption.

the authentication portion working, wanted @ encryption level.

i know tlsv1.2 , v1.1 supported alongside wih sslv3.

i use tlsv1.2 , nothing else.

tlsv1.2:!anull:!enull

is the correct cipher suite use?

information https://www.openssl.org/docs/manmaster/apps/ciphers.html seems not helpful...

can this matter?

i use tlsv1.2 , nothing else.

if want use tls 1.2 have configure protocol , not ciphers. limiting ciphers tls 1.2 ciphers drops support ciphers available since ssl 3.0 , still supported tls 1.2. depending on peer might end no shared ciphers way.

if still want restrict ciphers might try string tlsv1.2:!anull:!enull. make use ciphers newly introduced in tls 1.2 , implicitly enforce protocol. again, no guarantee server supports these ciphers if server can tls 1.2 protocol.

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri...
