This UDF implements the Secure Hash Algorithm, SHA-1, for computing a condensed representation of a message. When a message of any length < 264 bits is input, the SHA-1 produces a 160-bit output called a message digest (FIPS 180-1 / RFC 3174). This distribution contains full source code, a test suite, scripts, and documentation. README SHA-1 UDF package for Teradata Version 1.1 (2008-05-08) Copyright (c) 2008 Teradata Corporation. All Rights Reserved. This package is provided "as is". No warranty is provided. 1. Summary This package includes a UDF which generates SHA-1 message digest. For SHA-1 itself, refer RFC1321[1]. 2. Syntax hash_sha1(varchar) This function takes one char/varchar argument of arbitary length and always returns 160-bit hash value as hexadecimal char(40) format. It does not accept NULL value. 3. Installation 1 unpack the archive and go to src directory 2 start bteq and login to teradata 3 .run file = hash_sha1.btq 4 if you would like to validate hash value generated by the UDF, run sha1test_cre.sql, sha1test_ins.sql and sha1test_chck.sql in the test directory. 4. History Removed malloc() function which may cause memory problem in UDF. Fixed compilation issues on Windows platform. 5. Caveat You should not use these function to encrypt password without 'salt'. 6. Author KURODA Akira <akira.kuroda@teradata.com> Teradata Japan A.

This UDF implements the great circle distance algorithm to determine the distance in miles between two points expressed in longitude and latitude. This distribution contains full source code, REPLACE FUNCTION SQL, a test suite and documentation.

This UDF implements the MD5 message-digest algorithm. The algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input (RFC1321). This distribution contains full source code, a test suite, scripts, and documentation. README MD5 UDF package for Teradata Version 2.0 (2008-05-08) 1. Summary This package includes a UDF that generates MD5 message digest. For MD5 itself, refer RFC1321[1]. 2. Syntax hash_md5(varchar) This function takes one char/varchar argument of arbitary length and always returns 128-bit hash value as hexadecimal char(32) format. It does not accept NULL value. The name of the UDF is changed from there is an incompatibility against previous release. (see 4. History) 3. Installation 1 unpack the archive and go to src directory 2 start bteq and login to teradata 3 .run file = hash_md5.btq 4 if you would like to validate hash value generated by the UDF, run md5test_cre.sql, md5test_ins.sql and md5test_chck.sql in the test directory You can edit md5.h to customize hash generation. UDF_MD5_UPPERCASE: if set to 1 (default), generate MD5 result in upper case UDF_MD5_COMPAT: if set to 1 (not default), generate same result as previous release (see 4. History) 4. History Fixed MD5 algorithm that generates wrong result when the input length is 54 + 64*N bytes (N>= 0). Removed malloc() function which may cause memory problem in UDF. Fixed compilation issues on Windows platform. 5. Caveat You should not use these function to encrypt password without 'salt'. 6. Author KURODA Akira <akira.kuroda@teradata.com> Teradata Japan A.

The self extractable file includes the lobload application to load UDF's, SP's etc. into Teradata as part of installation.

Version: 1.0 - Created: 11 Sep 2007

Eight UDFs that search VARCHAR and CLOB string sources to see if they contain VARCHAR or CLOB string sets. Four of the UDFs are overloaded (named the same) to return the result in the form of VARCHAR or CLOB string while the other four UDFs are overloaded to return an INTEGER index into the string source if a match is found.
