ESP/AH support: k Linux 2.6+ kernel q for AH, AES-GMAC is negotiated as encryption algorithm for ESP n before version 2.6.33 the Linux kernel incorrectly used 96 bit truncation for SHA-256:

## $ ssh -Q mac # output would be something like hmac-sha1 hmac-sha1-96 hmac-sha2-256 hmac-sha2-512 hmac-md5 hmac-md5-96 umac-64@openssh.com umac-128@openssh.com So now in order to connect to target server with their choice of mac which your server doesn't support you have to explicitly provide one of the mac supported by target server.

For example, HMAC-SHA1-80 denotes HMAC computed using the SHA-1 function and with the output truncated to 80 bits. (If the parameter t is not specified, e.g. HMAC-MD5, then it is assumed that all the bits of the hash are output.) So simply get the HMAC (Java will give you 128 bits) and truncate it. HMAC Generator / Tester Tool. Computes a Hash-based message authentication code (HMAC) using a secret key. A HMAC is a small set of data that helps authenticate the nature of message; it protects the integrity and the authenticity of the message. Generate HMAC. Msg. Key. Choose Algo.

### PBKDF2_HMAC_SHA1(chosen_password) == PBKDF2_HMAC_SHA1(HEX_TO_STRING(SHA1(chosen_password))) Note that the smallest password of the two always has a length of 20 characters, because SHA1 hashes always consist of exactly 40 hexadecimal digits representing 20 bytes. One byte, i.e. two hexadecimal digits are used for each …
