According to the man page, the default is idea:
-c idea|des|3des|blowfish|arcfour|none
Selects the cipher to use for encrypting the ses-
sion. idea is used by default. It is believed to
be secure. des is the data encryption standard,
but is breakable by governments, large corpora-
tions, and major criminal organizations. 3des
(triple-des) is encrypt-decrypt-encrypt triple with
three different keys. It is presumably more secure
than DES. It is used as default if both sites do
not support IDEA. blowfish is an encryption algo-
rithm invented by Bruce Schneier. It uses 128 bit
keys. arcfour is an algorithm published in the
Usenet News in 1995. This algorithm is believed to
be equivalent with the RC4 cipher from RSA Data
Security (RC4 is a trademark of RSA Data Security).
This is the fastest algorithm currently supported.
