kSecAttrEffectiveKeySize

A key whose value indicates the effective number of bits in a cryptographic key.

Declaration

let kSecAttrEffectiveKeySize: CFString

Discussion

The corresponding value is of type CFNumber and indicates the effective number of bits in this cryptographic key. For example, a DES key has a kSecAttrKeySizeInBits of 64, but a kSecAttrEffectiveKeySize of 56 bits.
