Hi
You can create Routine(hard code Java class and methods) in 'Repository-Code-Routines'.
Then call the methods of Java SHA1 implement in Talend components such as tMap, tJava and so on.
Hope this will help you.
Best regards!

Here's some examples of methods that you can add to a Talend routine, for doing this.
public static String getMD5(String field) {
if(field == null) return null;

try {
java.security.MessageDigest md = java.security.MessageDigest.getInstance("MD5");
md.reset();
md.update(field.getBytes("UTF-8"));
byte[] digest = md.digest();
java.math.BigInteger bigInt = new java.math.BigInteger(1, digest);
String hashText = bigInt.toString(16);
// Now we need to zero pad it if you actually want the full 32 chars.
while(hashText.length() < 32 ){
hashText = "0" + hashText;
}
return hashText;
}
catch (Exception e) {
return null;
}
}

public static String getSHA256(String field) {
if(field == null) return null;

try {
java.security.MessageDigest md = java.security.MessageDigest.getInstance("SHA-256");
md.reset();
md.update(field.getBytes("UTF-8"));
byte[] digest = md.digest();
java.math.BigInteger bigInt = new java.math.BigInteger(1, digest);
String hashText = bigInt.toString(16);
// Now we need to zero pad it if you actually want the full 32 chars.
while(hashText.length() < 32 ){
hashText = "0" + hashText;
}
return hashText;
}
catch (Exception e) {
return null;
}
}
