unless you can accept a relatively low level of security and are running on modest hardware, you should generally choose an RSA key length of at least 2048 bits (current NIST recommendation); if you are running on recent dedicated hardware and/or require good security, then consider a key ...
My own conclusion is that 2048 is not a dead duck and using this key length remains a valid decision and is very likely to remain so for the next 5 years at least.The US NIST makes a similar recommendation and suggests it will be safe until 2030, although it is the minimum key length...
The defined keySize is 1024 Bit, which means I should get back a 128 Byte key. This is not how RSA keys work. RSA keys are stored as an ASN.1 structure, meaning that the length of the raw key bytes is only indirectly related to the key length in bits. You can learn more about ...
Also it is often limited to 3072, as it is the recommendation (https://www.keylength.com/) Note that the RSA verification is quite fast. Only the generation and signature are very slow. Contributor J0WI commented Apr 1, 2020 OPENSSL_TLS_SECURITY_LEVEL=3 requires at least 3072 bits. ...

Imho the keylength should be longer then 2048-bit ... Sorry, something went wrong. Copy link Contributor jdkasten commented Jun 20, 2015 If you truly want to be secure, you should be generating your own CSR and private keys. (Not allowing StartSSL to generate them for you). Start...
• The key length for an HMAC generation or verification must be between 112 and 4096 bits, inclusive. For HMAC verification, a key length greater than or equal to 80 and less than 112 is allowed for legacy-use. • The following restrictions apply to the use of PBKDF: – The minimum...
recommendation 6 For block type 02 the padding string is at least eight octets long which is a security condition for public key operations that prevents an attacker from recoving data by trying all possible encryption blocks For simplicity the minimum length is the same for block type 01 7 ...

For Quantum attacks like Shor's algorithm, RSA is more versatile. Yes, the key length is an issue, but only when that key is delivered in real-time in a TLS connection, when milliseconds matter. That's when Ec25519 is really preferred. We're bundling our RSA key with the extension -...
