Strong Encryption

[Souza, Clovis]

Does anyone knows which one is the strongest and which is the fastest
encryption algorithms
used in OpenSSH 3.7.1p2 from the list below

aes128-cbc,
3des-cbc,
blowfish-cbc,
cast128-cbc,
arcfour,
aes192-cbc,
aes256-cbc,
rijndael-cbc at lysator.liu.se,
aes128-ctr,
aes192-ctr,
aes256-ctr

Strong Encryption 
OpenSSH supports 3DES, Blowfish, AES and arcfour as encryption algorithms.
These are patent free.
Triple DES is a time proven and well understood cipher that provides strong
encryption.
Blowfish is a fast block cipher invented by Bruce Schneier that can be used
by people that require faster encryption.
AES <http://www.nist.gov/aes> is the US Federal Information Processing
Standard (FIPS) Advanced Encryption Standard developed as a replacement for
DES. It is a fast block cipher.
Arcfour is a fast stream cipher. It is believed to be compatible with
RC4[TM], a proprietary cipher of RSA Security Inc. 
Encryption is started before authentication, and no passwords or other
information is transmitted in the clear. Encryption is also used to protect
against spoofed packets.
