DGS-3100 Series Gigabit Stackable Managed Switch User Manual 3. Define the SSH global setting port number in the Port (1-65535) field. 4. Click . The SSH configuration is defined, and the device is updated. Defining SSH Algorithm Settings This SSH Algorithm Settings Page allows network administrators to enable a public key for SSH authentication encryption. The following authentication keys are enabled for SSH: Public Key Algorithm - Encrypts a cryptographic key pair composed of a public key and a private key. The private key is kept secret, while the public key can be distributed. The encryption keys are mathematically similar, but a private key cannot be derived from the public key. Messages encrypted with a public key can be decrypted with the matching private key. The following Public Key Algorithms are supported: - HMAC-RSA - Supports the Hash for Message Authentication Code (HMAC) mechanism utilizing the RSA encryption algorithm. - HMAC-DSA -Supports the Hash for Message Authentication Code (HMAC) Digital Signature Algorithm (DSA) encryption algorithm. Data Integrity Algorithm - Validates message authentication information transmitted between two parties which share the same key. The following Data Integrity Algorithms are supported: - HMAC-SHA - Supports the Hash for Message Authentication Code (HMAC) Secure Hash Algorithm (SHA) mechanism. - HMAC MD5 - Supports the Hash for Message Authentication Code (HMAC) MD5 Message Digest (MD5) mechanism. Encryption Algorithm - Generates authentication keys used to authenticate communications between different applications. The following Encryption Algorithms are supported - 3DES-CBC - Supports a block size of 8 bytes (64 bits); its key size is 192 bits long. The first 8 bytes cannot be identical to the second 8 bytes, and the second 8 bytes cannot be identical to the third 8 bytes. - AES128 -Provides a block cipher that encrypts and decrypts digital information. The AES128 algorithm is capable of using cryptographic 128 keys. - AES192 - Provides a block cipher that encrypts and decrypts digital information. The AES192 algorithm is capable of using cryptographic 192 keys. - AES256 - Provides a block cipher that encrypts and decrypts digital information. The AES256 algorithm is capable of using cryptographic 256 keys. - RC4 - Supports a cipher with an up to 2048 bits key size. 139
