Webb24 nov. 2016 · For the different key types, what are the recommended minimum -b bit sizes? This is not SSH specific, but generally key sizes are recommended by NIST in this document, page 12 (per 2015): RSA (2048 bits) ECDSA (Curve P-256) The Ed25519 does have fixed size so the -b parameter is ignored. Share Improve this answer edited Aug … Webb11 dec. 2024 · Theoretically, RSA keys that are 2048 bits long should be good until 2030. If so, isn't it a bit early to start using the 4096-bit keys that have become increasingly available in encryption-enabled applications? It depends. In case you're curious where we got the idea of 2048-bit encryption keys being safe to use until 2030, check out the …

Webb13 jan. 2011 · NIST Special Publication (SP) 800-57, Part 1 was the first document produced in this effort, and includes a general approach for transitioning from one algorithm or key length to another. This Recommendation (SP 800-131A) provides more specific guidance for transitions to the use of stronger cryptographic keys and more robust … Webb1024-bit RSA keys are equivalent in strength to 80-bit symmetric keys, 2048-bit RSA keys to 112-bit symmetric keys, 3072-bit RSA keys to 128-bit symmetric keys, and 15360-bit RSA keys to 256-bit symmetric keys. peterborough united fanzine

Webb14 apr. 2024 · Since its 2011 (or beyond), 80 bits is no longer recommended - we would need at least 112 bits of security. So we could use 3-key DES, 2048 bit Diffie Hellman for key exchange, SHA-224, etc. DES has been deprecated (even though 3DES is still viable) and AES-128 is readily available, so AES-128 and SHA-256 would be used. Webb4 jan. 2024 · NIST Special Publication 800-57 provides cryptographic key management guidance. It consists of three parts. Part 1 provides general guidance and best practices for the management of cryptographic keying material. Part 2 provides guidance on policy and security planning requirements for U.S. government agencies. Webb1 juni 2024 · The U.S. Federal PKI program states that: “Trusted Certificates that expire before January 1, 2031 shall contain subject public keys of 2048 or 3072 bits for RSA or 256 or 384 bits for elliptic curve, and be signed with the corresponding private key. peterborough united fans forum message board
