The actual cipher string can take several different forms.


It can consist of a single cipher suite such as RC4-SHA.


It can represent a list of cipher suites containing a certain algorithm, or
cipher suites of a certain type. For example SHA1 represents all ciphers
suites using the digest algorithm SHA1 and SSLv3 represents all SSL v3
algorithms.


Lists of cipher suites can be combined in a single cipher string using the
+ character. This is used as a logical and operation. For example
SHA1+DES represents all cipher suites containing the SHA1 and the DES
algorithms.


Each cipher string can be optionally preceded by the characters !,
- or +.


If ! is used then the ciphers are permanently deleted from the list.
The ciphers deleted can never reappear in the list even if they are
explicitly stated.


If - is used then the ciphers are deleted from the list, but some or
all of the ciphers can be added again by later options.


If + is used then the ciphers are moved to the end of the list. This
option doesn’t add any new ciphers it just moves matching existing ones.


If none of these characters is present then the string is just interpreted
as a list of ciphers to be appended to the current preference list. If the
list includes any ciphers already present they will be ignored: that is they
will not moved to the end of the list.


Additionally the cipher string @STRENGTH can be used at any point to sort
the current cipher list in order of encryption algorithm key length.

Some compiled versions of OpenSSL may not include all the ciphers
listed here because some ciphers were excluded at compile time.




 openssl ciphers -v ’ALL:eNULL’


Include all ciphers except NULL and anonymous DH then sort by
strength:




 openssl ciphers -v ’ALL:!ADH:@STRENGTH’


Include only 3DES ciphers and then place RSA ciphers last:




 openssl ciphers -v ’3DES:+RSA’


Include all RC4 ciphers but leave out those without authentication:




 openssl ciphers -v ’RC4:!COMPLEMENTOFDEFAULT’


Include all chiphers with RSA authentication but leave out ciphers without
encryption.




 openssl ciphers -v ’RSA:!COMPLEMENTOFALL’
