One of the oldest and most widely used public-key algorithms, RSA was first introduced in 1977 and is named after its creators (Ron Rivest, Adi Shamir, and Leonard Adleman).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A public key can be used to encrypt information or verify a digital signature, while a private key can be used to decrypt information or provide a digital signature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Read Also:<\/strong> <a href=\"https:\/\/cheapsslweb.com\/blog\/rsa-vs-aes-encryption\/\">RSA vs. AES Encryption: Key Differences Explained<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The security of RSA relies on the mathematical impossibility of solving a complex problem of factoring large composite numbers; this problem becomes more difficult as key size increases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">RSA keys are generally at least 2048 bits long, with 3072 bits recommended to ensure security over the long-term.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">RSA is still the default option for\u00a0certificate providers and widely used for\u00a0securing website connections using <a href=\"https:\/\/cheapsslweb.com\/\">SSL\/TLS Certificates<\/a> and email communications using <a href=\"https:\/\/cheapsslweb.com\/email-identity\">Email Signing Certificates<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is ECDSA?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">ECDSA or Elliptic Curve Digital Signature Algorithm is a newer public key cryptographic algorithm that utilizes elliptic curve mathematics to produce a secure and efficient digital signature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ECDSA relies on an elliptic curve discrete logarithm problem (ECDLP) rather than factoring large numbers like RSA. The ECDLP is a much harder problem to solve even for smaller key sizes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows ECDSA to provide the same level of security as RSA but with smaller keys, lower bandwidth consumption, and less computational overhead. In other words, a 256-bit ECDSA key gives you the same level of security as a 3072-bit RSA key.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also Read:<\/strong> <a href=\"https:\/\/cheapsslweb.com\/resources\/ecc-vs-rsa-certificate\">ECC Vs RSA Difference: Decoding the Cryptographic Algorithms<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because of its speed and small resource requirement, ECDSA is a great option for mobile devices, IoT systems, and modern web applications.
