RsaHashedKeyGenParams

RsaHashedKeyGenParams dictionary of the Web 加密 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 ,或 RSA-OAEP .

特性

name
A DOMString . This should be set to RSASSA-PKCS1-v1_5 , RSA-PSS ,或 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 NIST SP 800-131A Rev. 1 . 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 DOMString representing the name of the digest function to use. You can pass any of SHA-256 , SHA-384 ,或 SHA-512 here.

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

范例

See the examples for SubtleCrypto.generateKey() .
