This is NSS with a Cmake Buildsyste To compile a static NSS library for Windows we've used the Chromium-NSS fork and added a Cmake buildsystem to compile it statically for Windows. See README.chromium for chromium changes and README.trustbridge for our modifications.

+ *
+ * Please refer to the libpkix Programmer's Guide for detailed information
+ * about how to use the libpkix library. Certain key warnings and notices from
+ * that document are repeated here for emphasis.
+ *
+ * All identifiers in this file (and all public identifiers defined in
+ * libpkix) begin with "PKIX_". Private identifiers only intended for use
+ * within the library begin with "pkix_".
+ *
+ * A function returns NULL upon success, and a PKIX_Error pointer upon failure.
+ *
+ * Unless otherwise noted, for all accessor (gettor) functions that return a
+ * PKIX_PL_Object pointer, callers should assume that this pointer refers to a
+ * shared object. Therefore, the caller should treat this shared object as
+ * read-only and should not modify this shared object. When done using the
+ * shared object, the caller should release the reference to the object by
+ * using the PKIX_PL_Object_DecRef function.
+ *
+ * While a function is executing, if its arguments (or anything referred to by
+ * its arguments) are modified, free'd, or destroyed, the function's behavior
+ * is undefined.

+ * Cert
+ *
+ * A Cert represents an X.509 certificate. It can be created using the bytes

+ * of an X.509 certificate. Also included are functions to perform various

+ * (expiration), and signature verification.

+ * DESCRIPTION:
+ *  Checks whether the X500Name pointed to by "firstX500Name" MATCHES the
+ *  X500Name pointed to by "secondX500Name" and stores the boolean result at
+ *  "pResult". Two X500Names MATCH if they meet the conditions specified by
+ *  RFC 3280 (section 4.1.2.4). Namely:
+ *
+ *      "This specification requires only a subset of the name comparison
+ *      functionality specified in the X.500 series of specifications.
+ *      Conforming implementations are REQUIRED to implement the following
+ *      name comparison rules:
+ *
+ *      (a)  attribute values encoded in different types (e.g., PrintableString
+ *      and BMPString) MAY be assumed to represent different strings;
+ *
+ *      (b) attribute values in types other than PrintableString are case
+ *      sensitive (this permits matching of attribute values as binary objects)
+ *
+ *      (c)  attribute values in PrintableString are not case sensitive
+ *      (e.g., "Marianne Swanson" is the same as "MARIANNE SWANSON"); and
+ *
+ *      (d)  attribute values in PrintableString are compared after removing
+ *      leading and trailing white space and converting internal substrings of
+ *      one or more consecutive white space characters to a single space."
+ *
+ * PARAMETERS:
+ *  "firstX500Name"
+ *      Address of first X500Name to compare. Must be non-NULL.
+ *  "secondX500Name"
+ *      Address of second X500Name to compare. Must be non-NULL.
+ *  "pResult"
+ *      Address of Boolean result. Must be non-NULL.
+ *  "plContext"
+ *      Platform-specific context pointer.
+ * THREAD SAFETY:

+ * RETURNS:
+ *  Returns NULL if the function succeeds.
+ *  Returns an X500Name Error if the function fails in a non-fatal way.
+ *  Returns a Fatal Error if the function fails in an unrecoverable way.

+ * FUNCTION: PKIX_PL_Date_Create_UTCTime
+ * DESCRIPTION:
+ *  Creates a new Date of type UTCTime using the string representation pointed
+ *  to by "stringRep" and stores it at "pDate". The UTCTime restriction means
+ *  that the year can only be specified by the least significant two digits
+ *  (YY). As such, Only the years 1950-2049 can be represented. If "stringRep"
+ *  is NULL, this function creates a new Date representing the current time
+ *  and stores it at "pDate". Once created, a Date is immutable.
+ *
+ *  If YY is greater than or equal to 50, the year is interpreted as 19YY.
+ *  If YY is less than 50, the year is interpreted as 20YY.
+ *
+ *  The string representation of the date must be in the following form:
+ *      "YYMMDDhhmmssZ" where:
+ *
+ *  YY is the least significant two digits of the year
+ *  MM is the month (01 to 12)
+ *  DD is the day (01 to 31)
+ *  hh is the hour (00 to 23)
+ *  mm are the minutes (00 to 59)
+ *  ss are the seconds (00 to 59)
+ *  Z indicates that local time is GMT
+ *
+ * PARAMETERS:
+ *  "stringRep"
+ *      Address of String representation of Date.
+ *      If NULL, current time is used.
+ *  "pDate"
+ *      Address where object pointer will be stored. Must be non-NULL.
