import re
s='''qop="auth,auth-int,auth-conf",cipher="rc4-40,rc4-56,rc4,des,3des",m
axbuf=1024,charset=utf-8,algorithm=md5-sess'''
print s

all = re.findall(r'(.*?)=(".*?"|[^"]*?)(,|$)', s)
print all

for i in all:
	print i[0], "=", i[1].strip('"')


Output:
qop="auth,auth-int,auth-conf",cipher="rc4-40,rc4-56,rc4,des,3des",maxbuf
=1024,charset=utf-8,algorithm=md5-sess

[
	('qop', '"auth,auth-int,auth-conf"', ','), 
	('cipher', '"rc4-40,rc4-56,rc4,des,3des"', ','), 
	('maxbuf', '1024', ','), 
	('charset', 'utf-8', ','), 
	('algorithm', 'md5-sess', '')
]

qop = auth,auth-int,auth-conf
cipher = rc4-40,rc4-56,rc4,des,3des
maxbuf = 1024
charset = utf-8
algorithm = md5-sess
