REPROthe name the key is known by on the system where the REPRO DECIPHER isto be performed. This keyname must be the same one specified inINTERNALKEYNAME if REPRO DECIPHER is to be run on the same system.If REPRO DECIPHER is run on a different system, the specified keyname canbe different from the one specified in INTERNALKEYNAME orEXTERNALKEYNAME.This parameter is valid only when INTERNALKEYNAME orEXTERNALKEYNAME is specified. If the keyname is stored in the data setheader, it does not have to be supplied by the user when the data isdeciphered.Restriction: Keyname values identified by the SHIPKEYNAMES parametercannot be stored in the header. Therefore, you might want to avoid usingSTOREKEYNAME and SHIPKEYNAMES together because this could result instoring header information unusable at some locations.Abbreviation: STRKNUSERDATA(value)specifies 1-to-32 characters of user data to be placed in the target data setheader. For example, this information can be used to identify the securityclassification of the data.Value can contain 1-to-32 EBCDIC characters. If value contains a specialcharacter, enclose the value in single quotation marks (for example,USERDATA('*CONFIDENTIAL*')). If the value contains a single quotationmark, code the embedded quotation mark as two single quotation marks (forexample, USERDATA('COMPANY''S')).You can code value in hexadecimal form, where two hexadecimal charactersrepresent one EBCDIC character. For example,USERDATA(X'C3D6D4D7C1D5E8') is the same as USERDATA(COMPANY).The string can contain up to 64 hexadecimal characters when expressed in thisform, resulting in up to 32 bytes of information.Abbreviation: UDATADECIPHERspecifies that the source data set is to be deciphered as it is copied to the targetdata set. The information from the source data set header is used to verify theplaintext deciphered data encrypting key supplied, or deciphered from theinformation supplied, as the correct plaintext data encrypting key for thedecipher operation.Abbreviation: DECPHRDATAKEYFILE(ddname) | DATAKEYVALUE(value) | SYSTEMKEYspecifies whether you, PCF, or ICSF manages keys privately.DATAKEYFILE(ddname)specifies that the key is to be managed by you, and identifies a data setthat contains the private data encrypting key that was used to encipher thedata. For ddname, substitute the name of the JCL statement that identifiesthe data set containing the private data encrypting key.Abbreviation: DKFILEDATAKEYVALUE(value)specifies that the key is to be managed by you, and supplies the 1- to8-byte value that was used as the plaintext private data encrypting key toencipher the data.Chapter 30.
