Table 6: Cipher Strings and Meanings
Cipher String Aliases Meaning
DEFAULT The default cipher list, which corresponds to
ALL@STRENGTH
.
ALL All cipher suites except the eNULL ciphers, which
must be explicitly enabled.
HIGH Cipher suites with key lengths larger than 128 bits.
MEDIUM Cipher suites using 128 bit encryption.
LOW Includes cipher suites using 64 or 56 bit encryption,
but excludes export cipher suites.
EXPORT Includes cipher suites using 40 and 56 bit
encryption.
EXPORT40 Cipher suites using 40 bit export encryption only.
EXPORT56 Cipher suites using 56 bit export encryption only.
eNULL, NULL Cipher suites that do not offer any encryption at all.
Because the use of such ciphers pose a security
threat, they are disabled unless explicitly included.
aNULL Cipher suites that do not offer authentication, like
anonymous DH algorithms. The use of such cipher
suites is not recommended, because they facilitate
man-in-the-middle attacks.
kRSA, RSA Cipher suites using RSA key exchange.
kEDH Cipher suites using ephemeral Diffie-Hellman key
agreement.
aRSA Cipher suites using RSA authentication, which implies
that the certificates carry RSA keys.
SSLv3, SSLv2 SSL version 3.0 and SSL version 2.0 cipher suites,
respectively.
DH Cipher suites using DH encryption algorithms,
including anonymous DH.
ADH Cipher suites using anonymous DH encryption
algorithms.
AES Cipher suites using AES encryption algorithms.
3DES Cipher suites using triple DES encryption algorithms.
