Class Detail
KJUR.asn1.ASN1Util()
ASN1 utilities class
Since:
asn1 1.0.2
Method Detail
<static> {String} KJUR.asn1.ASN1Util.getPEMStringFromHex(dataHex, pemHeader)
get PEM string from hexadecimal data and header string This method converts a hexadecimal string to a PEM string with a specified header. Its line break will be CRLF("\r\n").
var pem  = KJUR.asn1.ASN1Util.getPEMStringFromHex('616161', 'RSA PRIVATE KEY');
// value of pem will be:
-----BEGIN PRIVATE KEY-----
YWFh
-----END PRIVATE KEY-----
Parameters:
{String} dataHex
hexadecimal string of PEM body
{String} pemHeader
PEM header string (ex. 'RSA PRIVATE KEY')
Returns:
{String} PEM formatted string of input data

<static> KJUR.asn1.ASN1Util.jsonToASN1HEX(param)
get encoded hexadecimal string of ASN1Object specifed by JSON parameters As for ASN.1 object representation of JSON object, please see newObject.
jsonToASN1HEX({'prnstr': 'aaa'});
Parameters:
{Array} param
JSON parameter to generate ASN1Object
Since:
asn1 1.0.4
Returns:
hexadecimal string of ASN1Object

<static> {KJUR.asn1.ASN1Object} KJUR.asn1.ASN1Util.newObject(param)
generate ASN1Object specifed by JSON parameters generate any ASN1Object specified by JSON param including ASN.1 primitive or structured. Generally 'param' can be described as follows:
{TYPE-OF-ASNOBJ: ASN1OBJ-PARAMETER}
'TYPE-OF-ASN1OBJ' can be one of following symbols:
newObject({'prnstr': 'aaa'});
newObject({'seq': [{'int': 3}, {'prnstr': 'aaa'}]})
// ASN.1 Tagged Object
newObject({'tag': {'tag': 'a1', 
                   'explicit': true,
                   'obj': {'seq': [{'int': 3}, {'prnstr': 'aaa'}]}}});
// more simple representation of ASN.1 Tagged Object
newObject({'tag': ['a1',
                   true,
                   {'seq': [
                     {'int': 3}, 
                     {'prnstr': 'aaa'}]}
                  ]});
Parameters:
{Array} param
JSON parameter to generate ASN1Object
Since:
asn1 1.0.3
Returns:
{KJUR.asn1.ASN1Object} generated object

<static> {String} KJUR.asn1.ASN1Util.oidHexToInt(hex)
get dot noted oid number string from hexadecimal value of OID This static method converts from hexadecimal string representation of ASN.1 value of object identifier to oid number string.
KJUR.asn1.ASN1Util.oidHexToInt('550406') → "2.5.4.6"
Parameters:
{String} hex
hexadecimal value of object identifier
Since:
jsrsasign 4.8.3 asn1 1.0.7
Returns:
{String} dot noted string of object identifier

<static> {String} KJUR.asn1.ASN1Util.oidIntToHex(oidString)
get hexadecimal value of object identifier from dot noted oid value This static method converts from object identifier value string. to hexadecimal string representation of it.
KJUR.asn1.ASN1Util.oidIntToHex("2.5.4.6") → "550406"
Parameters:
{String} oidString
dot noted string of object identifier
Since:
jsrsasign 4.8.3 asn1 1.0.7
Returns:
{String} hexadecimal value of object identifier
