A definition of the term "Secure Hash Algorithm" (SHA) is presented. It refers to a group of related cryptographic hash functions. It is mentioned that the most utilized SHA family is SHA-1 which is used in different security applications and protocols, including transport layer security (TLS...
Secure Hash Algorithm (SHA-1) produces a 160-bit hash value from an arbitrary length string. Like MD5, it is also used widely in applications such as SSH, SSL, S-MIME (Secure / Multipurpose Internet Mail Extensions), and IPSec. The main premise behind the security of SHA-1 is that it...
In IPsec proposals, the hash algorithm is used by the Encapsulating Security Protocol (ESP) for authentication. In IKEv2 IPsec Proposals, this is called the integrity hash. In IKEv1 IPsec proposals, the algorithm name is prefixed with ESP-, and there...

If it does not, you may see an error such as "Couldn't agree on a key exchange algorithm." For example, OpenSSH supports Diffie-Hellman Group 14 SHA256. HMAC-SHA256 integrity cipher support. The default is now the high security set of ciphers (hmac-sha1 and hmac-sha2-256 as ...
