RsaHashedKeyGenParams

The RsaHashedKeyGenParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into SubtleCrypto.generateKey(), when generating any RSA-based key pair: that is, when the algorithm is identified as any of RSASSA-PKCS1-v1_5, RSA-PSS, or RSA-OAEP.

Instance properties

name: A string. This should be set to RSASSA-PKCS1-v1_5, RSA-PSS, or RSA-OAEP, depending on the algorithm you want to use.
modulusLength: A Number. The length in bits of the RSA modulus. This should be at least 2048: see for example see SP 800-131A Rev. 2. Some organizations are now recommending that it should be 4096.
publicExponent: A Uint8Array. The public exponent. Unless you have a good reason to use something else, specify 65537 here ([0x01, 0x00, 0x01]).
hash: A string representing the name of the digest function to use. You can pass any of SHA-256, SHA-384, or SHA-512 here.

Warning: Although you can technically pass SHA-1 as a value here, this is strongly discouraged as SHA-1 is considered vulnerable.
