It is the 16 starting state for any life-cycle transitions. 17 18 =item newed 19 20 This state represents the PKEY after it has been allocated. 21 22 =item decapsulate 23 24 This state represents the PKEY when it is ready to perform a private key decapsulation 25 operation. 26 27 =item decrypt 28 29 This state represents the PKEY when it is ready to decrypt some ciphertext. 30 31 =item derive 32 33 This state represents the PKEY when it is ready to derive a shared secret. 34 35 =item digest sign 36 37 This state represents the PKEY when it is ready to perform a private key signature 38 operation. 39 40 =item encapsulate 41 42 This state represents the PKEY when it is ready to perform a public key encapsulation 43 operation. 44 45 =item encrypt 46 47 This state represents the PKEY when it is ready to encrypt some plaintext. 48 49 =item key generation 50 51 This state represents the PKEY when it is ready to generate a new public/private key. 52 53 =item parameter generation 54 55 This state represents the PKEY when it is ready to generate key parameters. 56 57 =item verify 58 59 This state represents the PKEY when it is ready to verify a public key signature. 60 61 =item verify recover 62 63 This state represents the PKEY when it is ready to recover a public key signature data. 64 65 =item freed 66 67 This state is entered when the PKEY is freed. It is the terminal state 68 for all life-cycle transitions. 69 70 =back 71 72 =head2 State Transition Diagram 73 74 The usual life-cycle of a PKEY object is illustrated: 75 76 =begin man 77 78
