To add a little more detail, the 2048 bit RSA key is something called asymmetric cryptography. It is used for validating identity (signing) and ensuring that only an intended recipient can access the information sent (encryption). It is composed of two pieces, a public key and a private key.

This command generates a 2048 bit RSA private key and stores it in the file www.mydomain.com.key. When prompted for a pass phrase: enter a secure password and remember it, as this pass phrase is what protects the private key. Both the private key and the certificate are required to enable SSL.

Sep 24, 2014 · RSA key length is increased to 2048 bits for AD RMS in Windows 7 or in Windows Server 2008 R2 Content provided by Microsoft Applies to: Windows 7 Enterprise Windows 7 Professional Windows 7 Ultimate Windows Server 2008 R2 Datacenter Windows Server 2008 R2 Enterprise Windows Server 2008 R2 for Itanium-Based Systems Windows Server 2008 R2 Foundation Windows Server 2008 R2 Standard Windows Server 2008 R2 Web Edition More sign verify sign/s verify/s rsa 1024 bits 0.000273s 0.000017s 3662.2 59513.0 rsa 2048 bits 0.001994s 0.000052s 501.5 19254.5 rsa 4096 bits 0.014438s 0.000219s 69.3 4560.3 So by doubling the key length, the time to sign a message increases by 7x, and the time to verify a signature increases by more than 3x. A 1024-bit RSA key invocation can encrypt a message up to 117 bytes, and results in a 128-byte value A 2048-bit RSA key invocation can encrypt a message up to 245 bytes RSA, as defined by PKCS#1,encrypts "messages" of limited size,the maximum sizeof data which can be encrypted with RSA is 245 bytes. 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 2048 refers to the bit length of the key which means that for the public key in a 2048-bit example, the big number, n, would be between 2 2047 and 2 2048. The maths involved is the same as in an example with a smaller key To add a little more detail, the 2048 bit RSA key is something called asymmetric cryptography. It is used for validating identity (signing) and ensuring that only an intended recipient can access the information sent (encryption). It is composed of two pieces, a public key and a private key. 2048 bit RSA currently is currently roughly strength equivalent to 128 bit AES. In terms of processing power/memory requirements for publicly known attacks both are out of reach of even government funded organizations.
