Description |
3DES |
168 |
These are well-proven, 168-bit, triple-encryption ciphers. Not
supported by products from Microsoft or Netscape. |
IDEA |
128 |
This cipher uses 128-bit keys but it is not commonly found in
web browsers or servers. In the USA and Europe a license from Ascom
AG is required to use these ciphers. |
RC4 and RC2 |
128 |
These ciphers use 128-bit keys, which normally offer a high
degree of security. Inside the USA a license from RSA is required
to use these ciphers. |
Export RC4 and RC2 |
40 |
These ciphers use 40-bit keys but are otherwise identical to
their equivalent 128-bit versions. Servers and browsers produced by
Netscape and Microsoft support these ciphers. Inside the USA a
license from RSA is required to use these ciphers. |
