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.
