This is the size in bits of the public key. Generally, the larger the key size, the more resistant the private key is to cryptanalysis (subversion of the cryptosystem).
We recommend that you choose a large key size (2046 or higher) if possible. Larger keys are harder to break and provide a more secure environment for your application, but take longer to process.
The following shows the key size, type, and ways the keys can be used:
Key Size | Type | Key Usage |
---|---|---|
4098, 2048, 1024, 768, 512 Bits | Unspecified, Encryption, Signature, Custom, SSL, or TLS | Key Encipherment, Digital Signature, Data Encipherment |
