versionAlgorithm (property)

The key version's algorithm.

Syntax

- (NSString*)versionAlgorithm:(int)versionIndex;
public func versionAlgorithm(versionIndex: Int32) throws -> String

Default Value

""

Remarks

The key version's algorithm.

This property reflects the key version's algorithm. For symmetric keys, this property will always be GOOGLE_SYMMETRIC_ENCRYPTION. For asymmetric keys, this value describes both the key type and the algorithm that must be used during cryptographic operations, and possible values are:

  • RSA_SIGN_PSS_2048_SHA256: RSASSA-PSS 2048 bit key with a SHA256 digest
  • RSA_SIGN_PSS_3072_SHA256: RSASSA-PSS 3072 bit key with a SHA256 digest
  • RSA_SIGN_PSS_4096_SHA256: RSASSA-PSS 4096 bit key with a SHA256 digest
  • RSA_SIGN_PSS_4096_SHA512: RSASSA-PSS 4096 bit key with a SHA512 digest
  • RSA_SIGN_PKCS1_2048_SHA256: RSASSA-PKCS1-v1_5 with a 2048 bit key and a SHA256 digest
  • RSA_SIGN_PKCS1_3072_SHA256: RSASSA-PKCS1-v1_5 with a 3072 bit key and a SHA256 digest
  • RSA_SIGN_PKCS1_4096_SHA256: RSASSA-PKCS1-v1_5 with a 4096 bit key and a SHA256 digest
  • RSA_SIGN_PKCS1_4096_SHA512: RSASSA-PKCS1-v1_5 with a 4096 bit key and a SHA512 digest
  • RSA_DECRYPT_OAEP_2048_SHA256: RSAES-OAEP 2048 bit key with a SHA256 digest
  • RSA_DECRYPT_OAEP_3072_SHA256: RSAES-OAEP 3072 bit key with a SHA256 digest
  • RSA_DECRYPT_OAEP_4096_SHA256: RSAES-OAEP 4096 bit key with a SHA256 digest
  • RSA_DECRYPT_OAEP_4096_SHA512: RSAES-OAEP 4096 bit key with a SHA512 digest
  • EC_SIGN_P256_SHA256: ECDSA on the NIST P-256 curve with a SHA256 digest
  • EC_SIGN_P384_SHA384: ECDSA on the NIST P-384 curve with a SHA384 digest

The VersionIndex parameter specifies the index of the item in the array. The size of the array is controlled by the VersionCount property.

This property is read-only.
