What RSA key length should I use for my SSL certificates?
Feb 26, 2009 · For security beyond 2030, 3072-bit RSA keys are recommended. NIST assigns an "effective strength" of 128 bits to 3072-bit RSA keys, versus 112 bits for 2048 bit keys. This means that it would take about 2 16 more computational effort to crack such a key.
key size - Is there much difference in a RSA-4096 over RSA-3072 …
May 26, 2021 · When considering RSA-3072, there are three potential future vulnerabilities: Someone amasses sufficient computing power to break a 3072-bit modulus using current algorithms. Someone invents a new algorithm that works faster. Someone builds a large and reliable Quantum Computer
Key size - Wikipedia
1024-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. [14]

Jun 19, 2019 · Key exchange: securely transport a secret key, used for encrypted communication later. RSA can work with keys of different keys of length: 1024, 2048, 3072, 4096, 8129, 16384 or even more bits. Key length of 3072-bits and above are considered secure.
RSA 3072 is 65,536 more difficult to factor than 2048?
May 16, 2016 · If RSA 3072 is equal to 128 bit symmetric and 2048 is equal to 112 bit symmetric then 128-112= 16 and 2^16= 65,536. In that case wouldn't this make 3072 more future proof against quantum computers or does Shor's algorithm mean they will both be equally useless?
Which key lengths should be used for certification authorities and ...
The German Federal Office for Information Security (BSI) recommends RSA key lengths of 3000 (3072) bits if the keys and the data they protect are to be used beyond 2022. The current recommended maximum for RSA keys with a Microsoft Certificate Authority is 4096 bits.
Security strength of RSA in relation with the modulus size
The security levels for RSA are based on the strongest known attacks against RSA compared to amount of processing that would be needed to break symmetric encryption algorithms. The equation NIST recommends to compute approximate length for key is found in FIPS 140-2 Implementation Guidance Question 7.5.
Code Signing Baseline Requirements to Require Larger Keys
When will DigiCert enforce 3072-bit RSA keys on Code Signing products? DigiCert will require 3072-bit keys or larger for new or renewed code signing certificates starting on May 27, 2021. You should speak with your DigiCert account representative about making the …

Jun 19, 2019 · For 128-bit security level, a 3072-bit key is required. The RSA key-pair consists of: The numbers n and d are typically big integers (e.g. 3072 bits), while e is small, typically 65537. By definition, the RSA key-pairs has the following property: (m^e)^d \equiv (m^d)^e \equiv m \pmod n (me)d ≡ (md)e ≡ m (mod n) for all m in the range [0... n)
