A fast home desktop can factor an RSA-512 key in 7-10 days, not 4 months. I have a haswell-E 6-core and can complete such a job in just under a week; a quad-core at 3.5ghz should take 10 days. 5. The estimate of 7-10 years of technological and software advances followed by 2-5 years for a factorization to be carried out is for RSA-1024, not RSA
Key Summary: Type: RSA 2048-Bit Public Key Identifier: 51:68:FF:90:AF:02:07:75:3C:CC:D9:65:64:62:A2:12:B8:59:72:3B Name: DigiCert SHA2 High Assurance Server CA Apr 03, 2014 · As advertised by the malware authors in the ransom demand, the files were encrypted with an RSA-2048 key generated on the victim’s computer. This was done using Microsoft’s own cryptographic infrastructure and Windows APIs to perform the key generation before sending it back in plain text to the attacker’s server. SSH host key fingerprint "ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx" does not mat 2015-11-24 19:20 I am using the .NET libraries and I am trying to connect to a server for the first time. Therefore encryption strength totally lies on the key size and if we double or triple the key size, the strength of encryption increases exponentially. RSA keys can be typically 1024 or 2048 bits long, but experts believe that 1024 bit keys could be broken in the near future.
In Windows Server 2012 New-SelfSignedCertificate don't have so many parameters. I want the certificate to be valid 5 years, the length of the public key to be 2048 and signature hash algoritm sha1. – bacclaudiu Jan 22 '18 at 13:26
Sep 24, 2014 · This article introduces a hotfix that increases the length of RSA keys for Active Directory Rights Management Services (AD RMS) to 2048 bits on a computer that is running Windows 7 or Windows Server 2008 R2. Currently, AD RMS uses RSA keys that are 1024 bits long for encryption. Additionally, the hashing algorithm is updated from SHA-1 to SHA-256. Azure SQL Database supports RSA 2048-bit customer-managed keys in Azure Key Vault. For more information, see Transparent Data Encryption with Bring Your Own Key support for Azure SQL Database and Data Warehouse . Router(config)# crypto key generate rsa general-keys The name for the keys will be: myrouter.example.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.

Sep 17, 2019 · -----BEGIN RSA PRIVATE KEY----- During CSR/Private Key generation, as a rule, it is possible to specify the key size. Nowadays most of the Certificate Authorities consider 2048-bit as an optimal key size for a RSA Private Key, since it provides a decent level of security and does not load the server’s CPU much.
