- **Description:** Use this Argon2 hash generator to create a Argon2 password hash. Hash text or encoded bytes and copy the complete salted result for verification.

## Parameters
- `input_text`: Input text.
- `hmac_key`: Salt (Optional / Auto-generated).
- `kdf_iterations`: Number. Iterations / Work Factor
- `kdf_length`: Number. Key Length (Bytes)
- `input_encoding`: `Hex` | `Hex (Ignore Non-Hex Characters)` | `Base64` | `UTF-8` | `UTF-16LE` | `UTF-16BE` | `Windows-1251 (Cyrillic)` | `Windows-1252 (Latin 1)` | ... (42 options)
- `output_format`: `Hex (lower)` | `Hex (UPPER)` | `Base64`

## Usage & Behavior
This Argon2 hash generator creates a salted password hash from text or encoded bytes. Use it to prepare development fixtures and understand the encoded value needed for verification. Password hashing is one-way; it does not encrypt a password for later decryption.

Use the steps below to create a Argon2 password hash.

1. Type or paste a non-sensitive test password into Input text.
2. Use Input Encoding: to describe the password: UTF-8 for normal text, or Hex or Base64 for encoded bytes.
3. Keep Auto / Live on to update the result as you edit. To work manually, turn Auto / Live off and click Run.
4. Read Argon2 Hash Result and retain the complete encoded string.
5. Click Copy to copy the result. Use Clear where shown, or a field's clear control, to clear the text.

- **Category:** Merge and split
- **Execution:** Client-side (JavaScript)
- **Related:** [Merge Two Columns](https://million.tools/merge-two-columns/)
- **Description:** Split a list into columns with a text to columns tool. Split rows by delimiter or whitespace into up to six outputs, with optional capitalization.

## Parameters
- `delimiter`: Split by.
- `input_text`: Insert list.
- `capitalize`: Boolean. Begin with uppercase letters.

## Usage & Behavior
Split a list into columns by separating each source row into fields. This text to columns tool places the first field in one output, the second in another, and continues up to six columns.

Keep one record per source row and choose the separator between its fields.

1. Paste the rows into Insert list. Keep each source record on its own line.
2. Leave Split by empty to separate whitespace-delimited items, or enter a literal separator. Clear Begin with uppercase letters if you want to preserve the original capitalization.
3. Click Split to process the current input.
4. Read Result — list 1 through Result — list 6. Each column holds the corresponding field from every input row; unused columns are empty.
5. Click Copy under the output you want to keep. Use Clear where shown to clear the text fields; option selections stay as set.

Check that each row has the same unwanted prefix or suffix length before applying a fixed character count.

1. Paste the rows into Insert list and set Number of characters to the count you want removed from each selected end.
2. Select Remove characters in the beginning, Remove characters in the end, or both. The default removes two characters from the beginning.
3. Click Execute to process the current input.
4. Read Result. When both directions are selected, the count applies independently to each end; a row with no characters left becomes empty.
5. Click Copy under the output you want to keep. Use Clear where shown to clear the text fields; option selections stay as set.

- **Category:** Merge and split
- **Execution:** Client-side (JavaScript)
- **Related:** [Compare Two Columns for Matches](https://million.tools/compare-two-columns/)
- **Description:** Merge two columns to combine corresponding rows. Join two columns with an optional space, lowercase the second value, and review rows left without a pair.

## Parameters
- `input_text`: Insert list.
- `needle`: Insert second list.
- `lowerize`: Boolean. Transform to lowercase.
- `add_space`: Boolean. Add space.

## Usage & Behavior

Align the two source columns before merging so each pair belongs together.

1. Paste the left-hand values into Insert list and the right-hand values into Insert second list, with one value per row.
2. Select Add space when paired values need a separating space. Transform to lowercase changes the second value in each pair while preserving the first value.
3. Click Merge to process the current input.
4. Read Result for paired rows and Rows remaining without a pair for the excess rows from the longer input. Merged rows and No pair summarize those counts.
5. Click Copy under the output you want to keep. Use Clear where shown to clear the text fields; option selections stay as set.

# Tool: Compare Two Columns for Matches
- **URL:** https://million.tools/compare-two-columns/
- **Category:** Merge and split
- **Execution:** Client-side (JavaScript)
- **Related:** [Compare Two Lists](https://million.tools/compare-two-lists/)
- **Description:** Compare two columns with a row by row comparison. Find matching rows and column differences, choose case sensitivity, and copy the comparison report.

## Parameters
- `input_text`: Insert first list.
- `needle`: Insert second list.
- `case_sensivity`: Boolean. Case-sensitive.

## Usage & Behavior
Compare two columns to check whether entries at the same row position agree. The row by row comparison returns a numbered report with both values and a match status, making it useful for checking aligned exports.

Keep related records on the same row in both inputs to make the comparison meaningful.

1. Paste aligned values into Insert first list and Insert second list, one value per row. Keep corresponding records at the same positions.
2. Leave Case-sensitive off to ignore letter case, or select it when capitalization changes should count as differences.
3. Click Compare to process the current input.
4. Read Row comparisons. Each tab-separated record contains the row number, the first value, the second value, and Match or Different.
5. Click Copy under the output you want to keep. Use Clear where shown to clear the text fields; option selections stay as set.

# Tool: Compare Two Lists
- **URL:** https://million.tools/compare-two-lists/
- **Category:** Merge and split
- **Execution:** Client-side (JavaScript)
- **Related:** [Combine Lists](https://million.tools/combine-lists/)
- **Description:** Compare two lists with a list comparison tool that returns combined unique values and list differences. Choose case-sensitive matching and copy each result.

## Parameters
- `input_text`: First list.
- `needle`: Second list.
- `case_sensivity`: Boolean. Case-sensitive.

## Usage & Behavior
Compare two lists to find values unique to either side and obtain a combined set of distinct entries. This list comparison tool helps review changes between exported labels, inventory codes, or keyword lists.

Compare membership across both complete lists, then inspect the combined values and the entries unique to each side.

1. Paste one value per line into First list and Second list. Row order does not determine whether a value belongs to both sets.
2. Select Case-sensitive to distinguish uppercase and lowercase values. With it off, values are converted to uppercase for comparison and output.
3. Click Compare to process the current input.
4. Review Only in the first list and Only in the second list. The field labeled Matches in both lists actually contains the combined unique values, including values present in only one input.
5. Click Copy under the output you want to keep. Use Clear where shown to clear the text fields; option selections stay as set.

1. Paste one item per line into Insert first list and Insert second list. Fill Insert third list (optional) only when you need a third part.
2. Leave Transform to lowercase selected to lowercase the second and third list items while keeping the first list unchanged. Select Shuffle list to randomize the output order.
3. Click Combine to process the current input.
4. Read Result and Number of combinations. Each output row joins one item from every supplied list with a space.
