Article summary

The senhasegura proxy system makes connections through protocols SSH or Telnet.

Attention

When using the Telnet protocol the connection from the vault to the device doesn’t use encryption, there’s only encryption when access is made from the user's station to the safe.

User’s workstation for the vault:

senhasegura supports the following encryptions:

Ciphers:

  • Poli1305.
  • AES256-GCM.
  • AES128-GCM.
  • AES256-CTR.
  • AES192-CTR.
  • AES128-CTR.

MACs:

  • hmac-sha2-512-etm.
  • hmac-sha2-256-etm.
  • hmac-sha2-512.
  • hmac-sha2-256.

KexAlgorithms:

  • curva25519-sha256.
  • ecdh-sha2-nistp521.
  • ecdh-sha2-nistp384.
  • ecdh-sha2-nistp256.
  • diffie-hellman-group-exchange-sha256.
  • rsa-sha2-256.
  • rsa-sha2-512.
Attention

Using weak algorithms reduces the security scope of the tool. Consult our experts on how to deal with legacy systems.
