RsaHashedKeyGenParams
RsaHashedKeyGenParams:
object
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.
Type declaration
hash
hash:
string| {name:string; }
A string or an object containing a single property called name with a string value. It is an identifier for the digest algorithm to use. This should be one of the following:
SHA-256: selects the SHA-256 algorithm.SHA-384: selects the SHA-384 algorithm.SHA-512: selects the SHA-512 algorithm.
modulusLength
modulusLength:
number
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.
name
name:
string
A string. This should be set to RSASSA-PKCS1-v1_5, RSA-PSS, or RSA-OAEP, depending
on the algorithm you want to use.
publicExponent
publicExponent:
Uint8Array
A Uint8Array. The public exponent. Unless you have a good reason to use something else, specify 65537 here ([0x01, 0x00, 0x01]).
