| 0 |
mailCipherNone |
No cipher has been selected. This
is not a secure connection with the server. |
| 1 |
mailCipherRC2 |
The RC2 block cipher was selected.
This is a variable key length cipher which supports keys between
40- and 128-bits in length, in 8-bit increments. |
| 2 |
mailCipherRC4 |
The RC4 stream cipher was
selected. This is a variable key length cipher which supports keys
between 40- and 128-bits in length, in 8-bit increments. |
| 4 |
mailCipherRC5 |
The RC5 block cipher was selected.
This is a variable key length cipher which supports keys up to 2040
bits, in 8-bit increments. |
| 8 |
mailCipherDES |
The DES (Data Encryption Standard)
block cipher was selected. This is a fixed key length cipher using
56-bit keys. |
| 16 |
mailCipherDES3 |
The Triple DES block cipher was
selected. This cipher encrypts the data three times using different
keys, effectively using a 168-bit key length. |
| 32 |
mailCipherDESX |
A variant of the DES block cipher
which XORs an extra 64-bits of the key before and after the
plaintext has been encrypted, increasing the key size to 184
bits. |
| 64 |
mailCipherAES |
The Advanced Encryption Standard
cipher (also known as the Rijndael cipher) is a fixed block size
cipher which use a key size of 128, 192 or 256 bits. This cipher is
supported on Windows Vista and later versions of the operating
system. |
| 128 |
mailCipherSkipjack |
The Skipjack block cipher was
selected. This is a fixed key length cipher, using 80-bit
keys. |
