The RsaHashedImportParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into SubtleCrypto.importKey() or SubtleCrypto.unwrapKey(), when importing 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


A string. This should be set to RSASSA-PKCS1-v1_5, RSA-PSS, or RSA-OAEP, depending on the algorithm you want to use.


A string representing the name of the digest function to use. This can be one of SHA-256, SHA-384, or SHA-512.

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


See the examples for SubtleCrypto.importKey().

Browser compatibility

Browsers that support any RSA-based algorithm for the SubtleCrypto.importKey() or SubtleCrypto.unwrapKey() methods will support this type.
