4 System Management Commands Field Encryption Table 4-16 show ssh - display description (Continued) Description The encryption method is automatically negotiated between the client and server. Options for SSHv1.5 include: DES, 3DES Options for SSHv2.0 can include different algorithms for the client-to-server (ctos) and server-to-client (stoc): aes128-cbc-hmac-sha1 aes192-cbc-hmac-sha1 aes256-cbc-hmac-sha1 3des-cbc-hmac-sha1 blowfish-cbc-hmac-sha1 aes128-cbc-hmac-md5 aes192-cbc-hmac-md5 aes256-cbc-hmac-md5 3des-cbc-hmac-md5 blowfish-cbc-hmac-md5 Terminology: DES - Data Encryption Standard (56-bit key) 3DES - Triple-DES (Uses three iterations of DES, 112-bit key) aes - Advanced Encryption Standard (160 or 224-bit key) blowfish - Blowfish (32-448 bit key) cbc - cypher-block chaining sha1 - Secure Hash Algorithm 1 (160-bit hashes) md5 - Message Digest algorithm number 5 (128-bit hashes) show public-key This command shows the public key for the specified user or for the host. Syntax show public-key [user [username]| host] username - Name of an SSH user. (Range: 1-8 characters) Default Setting Shows all public keys. Command Mode Privileged Exec Command Usage • If no parameters are entered, all keys are displayed. If the user keyword is entered, but no user name is specified, then the public keys for all users are displayed. • When an RSA key is displayed, the first field indicates the size of the host key (e.g., 1024), the second field is the encoded public exponent (e.g., 35), and the last string is the encoded modulus. When a DSA key is displayed, the first field indicates that the encryption method used by SSH is based on the Digital Signature Standard (DSS), and the last string is the encoded modulus. 4-41
